Metro looks like a great interface. Kudos to microsoft for coming up with something functional and pretty and completely different that what is already out there.
Now, if only they could fix Windows desktop and change the name....Windows has a lot of bad stigma attached to it, and its ugly.
They should really port the Metro look to the desktop....with a start tiles, little tiles for programs, pinned tiles and bars and hiding the file system tree. Then slim the OS down and cut a lot of the buggy ****, have it automatically download ONLY the drivers you need and autoupdate them. Maybe a central repository of drivers, distributed to pcs like software update? Essentially, upgrade the Metro team to being in charge of Windows. To increase performance, they could just make the tablets have the option to be Metro only.
If they release a slimmed down, hi performance, versatile windows 8+metro and support windows 7 for 2 years while business switch over to new hardware and software, that would be awesome. And for those that can't switch...well, I still see people running old versions of windows.
I like mac better than windows, buts its more of ease of use and style than an actual passion for the OS. I am glad MS is getting back in the game. They should bring everyone with them.
