Fastest Windows install ever. Rebooted, selected region, entered the key, went away from the desk for a quick smoke and after that it was already rebooting. Just a little more time for the configuration and a second reboot, can't have been more than 10 minutes all in all.
When I got into the OS I got the idea to try the Win key. It's been there for more than 15 years, and I've barely touch it before. Didn't make much sense just for opening the start menu, but it felt instantly natural for the start screen. I don't think I'll miss the start menu much. I'm already used to having the apps I use daily pinned to the taskbar, and the start screen gives a good overview that makes up for it being "further away".
Metro interface looks good but the features feel a little too large for a 22" screen with 1680x1050 resolution. I guess it's something to get used to and that the so-so contrast of a five year old panel isn't optimal, but it would have been nice if the type and graphics could adapt more to physical size rather than resolution. It will definitely look beautiful on a tablet, though.
I feel like I'm getting used to this, and unless there are any compatibility issues I don't think I'll go back to the Win 7 partition for anything but fetching stuff that has to be accessed by applications there.
