Alright guys, I truely can't decide. I currently have a PPC 17 G4 1.5ghz and its getting really slow for everyday life at college. I do a lot of web browsing and video watching. I also am an accounting major so excel is used quite a bit. With either of them I will most likely be running windows 7 off a partition or SD card so I can have my tax software. Coming from a 17 I feel that the 13 might be a bit small for my liking but at the same time i truly don't need the processing power of the i5 even though it might be nice to have for when I compress and encode videos from time to time. While i was in the shower today i was also thinking, would a 13 be able to run portals and half life 2 on a low to medium setting? I would like to play those games on my new laptop if possible. The price difference is huge and coming from a 17 the portability sucks so either one will be an improvement. What do you guys think? 13 base 2.4 1190 after tax or base 15 2.4 with hi res glossy screen 1900 after tax.
