I received one of the beta testing builds for Vista. i installed it on my iMac at home and its works ok except that there are some compatibility problems with some programs. also, i cant use my keypad and the volume control has to be operated with my speakers volume control and not the one the keyboard. things like that dont work but its no big deal. the problem is that when i tried to install vista on my computer at my office it said that my graphics card wasnt new enough to run vista and so it wont install properly. i am using a dell in my office thats only a few years old and a basic model with 1gb of RAM. does this mean that 3/4 of all windows users are going to have to upgrade their graphics cards just to install vista??!! thats crazy!
