I've been flip flopping around some between the 13" Air and 13" Pro, and had a few questions for you Pro users. I've heard that the Pro is nearing the end of its cycle. Would it be bad to buy one at this point? I need/want a computer now, but don't think I could wait until Q1 of next year... What do you guys think of the lower resolution on the Pro compared to the Air? (1280x800 vs 1440x900) This is the only thing that really worries me about buying the Pro, is it that big of a deal. How hard is it to upgrade the Pro yourself? Are there many compatibility issues, or do most parts work well? And last, how does Lion run on the 13" MBP?
