I'm considering purchasing an EOL or refurb unibody Macbook and am well aware that it has no Firewire and that the max memory it will take is 4GB. Aside from that are there any other differences (aside from processor speeds) between these models and the new 13" Pro models? I'd heard the new screens were better in the Pro, can anyone tell me how bad the old screens really are - what is the problem with them? Are they all bad? Are they the same standard or better than the White MacBook? Also, is the 2.4 model generally considered to be worth an extra $250 (I'd probably be upgrading hard drive myself anyway so that is less of a factor)? It would also be interesting to hear from anyone who has one of these and their positive and negative experiences with it.
