Mostly iLife type things. Quicken, Office stuff like that. I only carry it with me when I travel and that is somewhat rare these days. I just figured out the two display thing so that is kind of nice. When VPC 7 comes out and is anygood..... I plan to use it for most of my school stuff when I am not at my desktop. For everday apps, the powerbook is as good if not better than my pc, the only thing my pc has over my powerbook, is the ability to use matlab and pspice and the gaming performance is really good. I really don't want to have to go get another license for the mac, as far as matlab is concerned. I work as an engineer full time and also am trying to finish up my MSEE. I was just thinking if i use my powerbook like a desktop, then why didn't i just get a desktop.
