I love windows 8! the boot is so fast too! Even made a youtube video comparing cold and normal boots [video=youtube;_dovt-dCiAY]https://www.youtube.com/watch?v=_dovt-dCiAY[/video]
Nice boot up times! I hope the tablet UI will not be replacing the start menu, i dont think it will to be honest as the build is just a preview of what developers can expect.
boot times are fast, using it on my carPC atm and it's one of the best interfaces I've come across for small screens!
