My nephew (12) is looking for a computer he can take to school (he uses speech software for a learning issue). He is looking at the new MB (aluminum), or the early 2008 mbp 15 with the 256-8600 video. Other than school, he also wants to play games-nothing extreme at this point. At home, he will probably plug in to an external LCD. So, the following questions: 1-anyone have experience with the difference in size and bulk between the 13 and 15 (also difference between 4.5 and 5.4 pounds)? 2-Is the new touchpad significantly better than the multi touch on the mbp? 3-How does the new onboard video on the mb compare to the dedicated 256mb 8600m gt in the MBP, not only for viewing, but output to external? We've already considered the difference in ports (firewire 400/800 vs only usb2, etc.), but any further ideas about that are welcome. We're leaning toward the early 2008 MBP refurb, and no, he doesn't do windows (though if I get him a good price, he might sweep my patio...) Thanks!
