Yes you can dual boot W8 and W7. I am right now, although i havnt logged into W7 in a few days. I think it is worth the change, not only because of the Metro UI, but because W8 is simply faster in loading and processing time. Do you mind if i ask which program the mini Metro UI is on the screen shots? And where can i download it please? I did a google search for Onomino and Rain Meter but couldnt find anything related to Metro UI.
