The Metro interface/GUI and Metro style apps (including Metro App Store) is really what seperates Windows 8 from Windows 7. Windows 8 Desktop mode and everything "under the hood" is remarkly similiar to Windows 7, and in that respect, very little has changed.
After playing around with Windows 8 for some time I realized that Windows 8 is entirely superfluous, redundant and reactionary. It is not revolutionary or even evolutionary. It is two major step backwards and the changes being shoved down our throats are entirely Microsoft's reaction to threats like Google, Amazon, Apple, etc and have nothing to do with true innovation for the end user.
These days if you are like most people regardless of the form factor of your computational device (desktop, laptop, netbook, tablet) you are spending most of your time on the internet or connected to some network. And more likely than not, after booting up your computer and getting into the operating system, you are probably also spending a majority of that time in a web browser window interaction with different sites, software as a service services, and also increasingly with baked in browser apps and utitlies such as in the Google Chrome web /app store. Back in the Firefox days we had the concept of browser "extensions" to expand the functionality of a web browser, but increasingly in modern browsers the app stores sport fully functional standalone programs that are socially connected through the internet and replace the operating system itself . Well not technicailly, but browsers are becoming like an operating system on top of the host operating system, and just like the job of any OS is to abstract away the underlying hardware, browsers abstract away the operating system so that chrome app works in Windows as well as it works on Linux or Mac, etc. Since browser apps are both hardware and operating system agnostic/independent, and Google now keeps track of everything across browsers in your Google account, increasingly this is weakening the Windows OS hegemony.
IE used to have 90% marketshare in its heyday. These days Chrome has surpassed both Firefox and IE in terms of browser usage marketshare and mindshare and has no signs of relenting anytime soon. Microsoft has tried to play catchup with the release of IE 9 but it is too little too late and not working. Its bing/yahoo search engine still is only making glacier inroads against Google in the search engine wars... Microsoft's two crown jewels and revenue cash cows (Windows and Office) are both being threatened on multiply fronts.
Microsoft's answer is Windows 8. And specifically the Metro interface and Metro style apps and Metro App store. While Metro can be used with keyboard and mouse, its true purpose and intent is geared towards TOUCH. In fact, Metro is synonymous with TOUCH. All smart phones, tablets, pads are touch sensitive with multitouch support. While it is certainty possible to use Metro with Touch on a desktop with monitor that supports this, there is no practical advantage to doing so. Nothing beats the productivity of mouse and keyboard with classic user interface on a large desktop form factor and display size.
Windows 8 is really an operating system with an identity crisis. It wants to play catch up to the mobile and tablet world, while also playing catch up to the "app store" concept/business model and catching up on the grounds it lost in the browser wars. But as it stands, Windows 8 is actually Windows 7 (in desktop mode) with an after-the-fact baked-in and layered-on Metro GUI that feels akin to an operating system on top of an operating system, i.e. a web browser!
In one fell swoop Microsoft has reversed 25+ years of PC tradition and eradicated the "start menu" and replaced it with what basically amounts to a modern web browser app store. The original purpose of the "start menu" was to categorize, organize and list the multitude of programs and applications that were installed on a user's system. New Microsoft has done a bait and switch and using the familiarity of the "start menu" to force users to be exposed to its "operating system within an operating system" the aka Metro App store. Since on boot-up the default screen is the Metro screen and even in Desktop mode users still have to frequently revert back to Metro interface to get work done or switch to different applications, etc what this really amounts to is Microsoft turning its back on the traditional "open" platform of the PC and using its PC marketshare hegemony to force users to adopt Microsoft's other wares like hotmail, skydrive, office 365, bing, IE10, etc etc etc... While Microsoft has backwards compatibility with "legacy" application support through what is known as "desktop mode"... what is really happening is Microsoft wants to position itself in a new software and computing paradigm where the operating system becomes the web browser (through the Metro interface, Metro style apps which are forced onto and inflicted upon the user via a trickery substitution replacement of the traditional "start menu" ) and where the operating system also serves the role of software delivery platform (cutting out retailer middleman like Best Buy, Wal-Mart, Fry's Electronics that offer the "boxed" software and also cannibalization of digital retailers like Steam, Amazon, Google Play, that offer licensed downloads of third party software and content, etc) A lot of people buy software from Amazon.com or download applications or tools from download.com and a variety of different sources. With Windows 8 and Metro, Microsoft is in one fell swoop making the PC a closed platform and copying Apple (just like they did twenty years before with the DOS OS copying Apple's GUI interface) and trying to get some sloppy-seconds cheap-action by double-dipping -- offering a paid OS but with artificially hard-coded mobile/tablet restrictions and limitations. They are pushing METRO to the forefront and relegating "desktop mode" to some "legacy" world that they wish would die away and be forgotten... and all the while they will get a 30% cut of all metro apps, and be the gatekeeper of what you can and cannot install, run, do on your own computer, and make you pay for the privilege to "upgrade" to the newest and greatest: Windows 8. Right... Anyone with two brain cells to rub together can predict how this will turn out. This ain't 1995 nomo and Microsoft's monopolistic tactics doesn't work. Last time I checked Internet Explorer no longer had 90% of the marketshare, no not even close. lmao And seriously, those interested in tablets, smart phones, etc will get either iOS if they want quality and don't mind shelling out the big bucks for an overpriced luxury brand product, or side with the darkside of evil and cave to Google's Android and Chrome + Chromium OS universe ... And don't forget the Amazon kindle/fire..... Who the F*** needs Metro-sexual "Star Trek Original Series"-looking and "Windows 1.0"-reminiscing interface and app store?
Microsoft's hope is to get to the user before the browser does. Nowadays when a user boots up the PC, the first thing he usually does is fire up the web browser and check his social networking, email, and does his applications online or through apps downloaded via the browsers baked-in app store. The OS has been abstracted away and relegated to the position of hardware itself, basically becoming a mere commodity and an afterthought. People no longer pay that much attention to their underlying operating system because the browser has become the center of the internet and even computing universe. This is Microsoft's worse fear... but with Metro interface, once the PC boots up the user will be forced to encounter Microsoft's baked-in Metro App store and Microsoft's suite of its own apps like Mail (hotmail), Video (Windows Media Player), and in essence Microsoft is hoping that with Metro it will get to the user before the browser does. (before Google does) This is also why Windows Live, Hotmail, Skydrive etc will be an integral part of the Windows 8 experience... and you are basically coerced into signing up for, and using, a Windows online account. This is a battle between Microsoft hegemony and Google hegemony. With Windows 8 Microsoft is hoping that user will do everything in this "new start menu" and that the Metro interface will allow this new operating system to replace or at least compete with many of the extended features of modern browsers and reverse the trend of the "browser becoming the OS"... (by getting to the user with an OS baked-in "app store" before the actual browser can get a chance to do the same!)
Microsoft has so far failed to get into the mobile market, the tablet world and the "app store" game... (sidenote: funny how Google Android marketplace is now called "Google PLAY") so it is using the only weapon it has to force itself into the marketplace: by converting its PC operating system and transforming it into a mobile OS, a tablet OS, with a baked in App Store that we can't get rid of. And by doing so, by catering to the lowest common denominator, Microsoft is killing off the traditional PC ecosystem as we knew it to be, and these desperate tactics come from the expense of user productivity and efficiency. Instead of putting the end user interests first, this is bona fide case of Microsoft coming out with a new operating system in a very reactionary way to solve Microsoft's own failures and problems, totally irrespective and irregardless of what the end user actually wants or needs.
For various reasons I'm fully confident that Windows 8 will fail MORE miserably than Windows Vista + ME added together. In fact if it wasn't for ipv6, directx11, more efficient multiprocessor and multicore support, and 64-bit (XP has a 64bit version but its really not usable) support then I'd still be on Windows XP Professional with service pack 3. But as it stands, I predict that Windows 7 will see a longer longevity than even the very successful Windows XP. Corporate world is just now finishing transitioning from XP to Windows 7. They will not even look at Windows 8. Operating systems have basically matured, especially in the desktop and traditional pc world. We will never need anything more than ipv6 after transitioning from ipv4 (and even this will take probably 10-15 years!) and to transition from 32-bit OS and applications to 64-bit OS and applications will also be the last time we do this. Most graphical applications and pc games can't even take full advantage of directx10 (heck, a lot of new games don't even max out or take advantage of everything directx9 has to offer) and I really don't see any "killer games" or "killer 3d apps" on the horizon or even in the foreseeable future that will really necessitate or require anything more than directx11 in its current form. And so as for myself, I will personally be using Windows 7 until 2030. At which point I will re-evaluate and take a look at Windows 9/10 or maybe by that time Linux, Mac, whatever is better or best by then.
It is a sad sad world we live in where Microsoft has fallen so gracelessly from its one great heights. Windows 7 is dead. Long live Windows 7.
BTW. How is the "freemium" "DLC store" strategy working out for Microsoft FLIGHT (2012)? Pathetic. That is what happens when Microsoft turns its back on 25+ years of tradition and canned the Aces team, killed the Flight Simulator franchise (older than MS itself!) and then sold the FSX source code to Lockheed Martin (Prepar3d) just to make a quick buck, then try to monetize that code further by throwing a tiny bucket of money to a new dev team to develop FLIGHT (2012), when they quickly realized how expensive and time consuming it would be to make Orbx class scenery for the entire world they released a freemium (DEMO) with only the main island of Hawaii and a single Honda on Wings (Icon A5) and said this no-SDK, no-cockpit, no-ATC, no-AI, no-Traffic, no-FMC Flight arcade game was the wave of the future. They forgo releasing an SDK and kicked all the third party developers like PMDG out and pimped the Flight App Store as the way forward.... Well that move did nothing but solidify FSX as the platform for the next 10+ years. I can draw many parallels between the FSX-> FLIGHT and Windows XP/7 -> Windows 8. As I see it, regardless of whether or not the PC platform is dying, Windows 7 will be the last operating system on the PC for most people, especially those that know a thing or two about computers at all.
