hey there, I've been contemplating recently (as most mac users do) about switching my 2 year old MBP (2.2 ghz, 2gb ram, 8600m) to the new MBP (15" 2.8, newer gfx, touchpad and a few minor details). I've been eying the ebay prices for some time and my particular model (with charger, snow leopard, original accessories but w/o box) is valued at about 700gbp. Perhaps people might disagree with me here - how much is it really worth ? My main point / question is really at what point should I ditch the existing MBP in favor of the new mbp - does it really offer me that much of a benefit at this time to upgrade? I'd sure like the new graphics card in there (is it really that much better?) but I'm not sure there's a significant enough difference there. On the other hand if I wait much longer the MBP will become pretty devalued and not get me much back for the new and improved MBP - maybe apple's going to improve them soon anyway? hmm, yes. Interesting indeed!
