alot of uneeded security... i swear, at every turn it asks you for permission, even askes permission to ask permission lol... it kinda gets annoying, but you get used to it really quick.

erm, it has small compatibility issues with a wide arrange of programs... usually solved just by going to properties and checking off "run compatible with windows xp sp2." with one game so far (out fo quite a few) i have to right click and click run as administrator" to get the game to work right, but other then that, games really have no problems.

it has alot of bugs... they can be pretty annoying... i've told them in another thread (windows vista bugs), nothing really major tho, a simple restart takes care of 'em. there's been a few updates but not much... so i'd still hold off if you could o.0
