Hi, I'm not the OP, I'm one of the other 4 people outside of MS who likes Metro.
I find it much more elegant than what I used before, which was a start menu with too many icons, leading me to have a dozen usual shortcuts on the desktop itself. That "desktop" way of using the computer also lead me to keeping a bunch of current documents on the desktop folder, which required regularly cleaning up. Soon enough I fall behind on those tidying up chores and start dropping everything in a folder just to hide the mess when I present at customers.
With Windows 8 Metro, I just store everything in the right library folders and it gets indexed for quick finding and retrieving. The Start screen shows me useful stuff before I start any application. The UI guidelines for Metro are suitable for simplified apps, which are a welcome improvement over having everything and the kitchen sink on the main screen, plus an Advanced Settings tab. Programmers can dislike web designers as much as they like, but the fact is that "Apps", Apple style, did offer improvement over what is still common in the "PC" world.
In parallel, I find it that the Windows Store is a good replacement for relying on Google search results to decide what to install on my PC when I need something new. Do a search for [some application name] APK and see the same old crap happening with Android apps. On balance, I think app stores are a good thing.
I got Windows 8.0 soon after it was released, as a cheap upgrade to Windows 7. I think it compares well to what Apple did with OS X and iLife a few years ago. It works fine and the account sync across devices is a really nice to have. So much, that Firefox had it before for a much smaller scope of use.
Recently, I asked my company to upgrade W7 to W8 on my work laptop (Mods: "+ 1, Funny"). Since there are work-related restrictions in relation to the use of MS accounts, I find tha I'm using only part of what W8 offers. Unsurprisingly, I have to fight MS apps on occasion and it is kind of accomodating in relation to signing on to separate applications with or without the Windows account. On my home PC, I leave more settings with their defaults on and overall it's more comfortable to use.
The key thing is that Windows is no longer just an OS that sits in your PC. It is an OS + applications + a bunch of online services so that it competes with the equivalent from Apple and Google. I understand that /.rs would like stuff to be like in the old days, but that's not what the market says: PC sales are dropping and tablets/smartphones are selling more in its place. Folks at Microsoft would be stupid to drop Windows Metro + online services just to please the "desktop" users. I think that it won't take long until we accept that the "PC market" is not separate from the smartdevice market, leading to about 25% of PCs sold being OS X/iOS; 25% with Android/Chrome and Wintel devices will have something like 40%, with a tendency to go down.
