Hi everyone! I am thinking of buying a 15" PB during this week. I will mostly be using office programs and movie watching on the PB. Because this is going to be my first mac I have some questions: 1) I just wonder if there is a big difference between 128 vs 64 MB in Vram when you run on dual monitors? (does Tiger/Exposé run smoothly?) 2) I also wonder if its worth to buy the high-end or if I should pick the low-end 15" but with SP? 3) How much harddisk space do you have left after the Tiger has been installed? 4) Do you know any good backpack for a 15" PB. It should have plenty of room for books while I am in collage. 5) How long do you think the delivery will take if my order will include: iPod 20Gb - engraved Powerbook 15" - BTO MightyMouse Looking forward to switch to mac, finally!
