Ok, so i have downloaded the windows vista beta 2, and i am going to burn it on to dvd and install it, how stable will it be? will i be able to use it in confidence that it will not keep crashing? when istalling it i am asuming that i will have to format my hdd, so i will have to back up everything else i have? is anyone else useing vista and can tell me how they are finding it? cheers
