My apologies if someone has already posted this comparison, but I've been browsing threads since the announcement and haven't seen this addressed specifically. I know the uMBP 13" screens are now officially much better, but has anybody has a chance to compare a 10/08 uMBP 15" screen with the new uMBP 15" screen? I was looking at upgrading to a unibody, and while the new models are nice the price drops on the 10/08 model are very tempting. The only thing that's pointing me towards the new one is if the screen is really that much better and I'm wondering if the old one can run more than 4GB of RAM after the software updates. Anyway, has anyone compared the new and prior unibody screens on the 15" MBP and is there any significant real world improvement?
