I'm a high school senior going off to college in a few months and I have begun searching for a laptop. For most of my life I have only worked with PCs and it's come to the point where I'm at a crossroads. Do I defect from Windows? Or do I stick with them? I have done some searching and I really like the MacBook. I am a bit weary with software compatibility at school. I know I'll receive iWork and all that jazz. However, my intended course of study may require me to use software that may not be written for Apple. Question 1 is this, if I get Windows Vista Ultimate (I can imagine the groans now) pre-installed on my machine, how does running a program in Vista work? Is the HD partitioned or am I running it on an "imaginary" OS? When running a program in Vista on the Apple, will the OS be slower than an actual PC with vista as the main OS? With the resource hog, vista, on the machine, should I opt to get the 2 gig of ram? That should be it for now. THANKS!
