its strange. I havnt found any MAJOR bugs in Vista. Actually, the only bug ive found so far is that when I click on the shut down button in the start menu, it fades to black but it comes back after a minute. I just turn it off with the off button. Its incredibly stable and the firewall has blocked a bunch of stuff so far. I havnt crashed it yet and thats quite impressive :D. Maybe its because Im using the OEM version but I dont think that makes a difference. That Aero thing is nice though although I dont really care for the Flip 3D thing but the glass effects are aesthetically pleasing. I will update when I find anything else..
