ya man ..vista is the memory sucker!!...but sunyata ..i too downloaded the office 2007 but i didnt have any problems.. and yeah there are compatibility problems but i think there are not much of softwares that dont work with vista ,,,everything i need works in vista.. vista really has cool graphics compared to xp..so if u have higher RAM then i think vista is better than xp...and reverse engineer u dont have to double confirm..u can turn off the user account control
