I'm selling my cracked-glass MBP on eBay (linky) not only because I cracked the glass in front of the screen, but because I need a larger display. The 1280x900 isn't cutting it for me. I start college in two weeks as a CS major. It's good for light-duty usage, but when programming or even viewing web pages, things are super cramped. It drives me nuts and I can't get things done. I have shot right past power-user and I now need a mobile powerhouse. However, I am a poor college student. The 13" is no option for me. I cannot afford to buy a new 15" or 17" MBP, but my budget is $1400. In all honestly, I would swap to Win7 if I didn't write iOS apps. So here lies the question: 15" or 17"? - On eBay older 15" unibody MBPs can be found for around $1100+. I don't think the screens are big enough. - There are plenty of non-unibody 17" MBP with luscious 1900x1200 resolution, but portability becomes a concern. Battery life concerns me; however, I do like that I can swap batteries. I've never found that the battery life is as outstanding as Apple claims. My old Core Duo 15" MBP had battery life as good as my 13" MPB. Despite age, the majority of them in terms of clock speed are faster than my 13" MBP. Thanks for your help in advance!
