oh my word why?
Windows 7/8 totally sucks for anything useful. I've had the unfortunate 'pleasure' to eval windows 8, and if that is truly the direction Microsoft wishes to go then I shall dump it for Linux. I can't understand what moron thought it would be great to design an os that is only truly usable on a touchscreen device, whilst ignoring those of use with normal computers.
Ubuntu went this route and it is losing users, Gnome 3 developers went this route and they are losing users just as fast. If Windows insists on joining them then it's goodby Windows, and hello to Linux at least with decent distros that don't all drink the touchscreen cool aid.
