Well I bought my MBP in August and I have really enjoyed it so far and I really am loving OS X...but recently I have gotten the urge to build a new custom PC, so I am going to go ahead and pursue that. However I do want to keep my laptop for portability and to use OS X. I bought the MBP as a desktop replacement, but now with a new desktop PC, I am thinking I might want to get something more portable since I don't need the power of the MBP anymore (not that the macbook is lacking much besides video power). The only problem I face is that I have to buy new products (just the way I am) so I will probably just break even if I were to sell my MBP and get a black macbook (don't like the white much). So essentially I would only gain 100-200 dollars by doing this, but would lose the bigger screen, dedicated video (no big deal at all), and aluminum design. But a plus would be I would also get leopard on the new macbook which I do no currently have on my MBP. I just wanted to gather everyones opinion to maybe help me make my decision. By the way, I was guessing of getting ~1500 for my 2.2, 2gb, 128mb 8600gtm, macbook pro which is in perfect condition? Does this sound about right? Thanks.
