Hi all, first post. I have had a 17"MBP 2.4ghz Intel Core 2 Duo for YEARS now and have been hanging on for the spec bumps as I have needed to replace for a while but was conscious improvements were coming. I have quite a few questions and was hoping for some informed answers, but thought best to ask here rather than the apple store so I can get a more genuine and less sales orientated response! Question 1 - Proper Refresh? I know there are rumours of redesigned models in spring but are we expecting them to be worth waiting for? My eyes are suffering due to the loss of backlight on my MBP and I'm thinking replacing now is a priority. Question 2 - Processor Bump I generally look to future proof my purchase by spending a bit more to make sure it will last. Im looking at bumping the spec up to 2.5ghz quadcore as I know the 'brain' is the only bit I can't really bump later. Any tech heads know if the difference between quad 2.4 and quad 2.5 will be noticeable? Question 3 - Mac RAM vs Crucial RAM In the past I have used crucial for ram upgrades; but I never had the apple care. Whenever I have spoken to staff in apple stores they have always agreed that crucial made more sense from cost point of view, and that it was the same as what they use / same quality... a - if i get crucial ram does anyone know if I void apple care? b - in the unibody macbook pros is it as easy to install ram yourself? Question 4 - Battery Obviously with my 'archaic' macbook pro Im used to the battery housed to the exterior and being fully removable. I'm on my 3rd or 4th battery with this macbook pro as they have always swollen and split eventually. I worry with the battery being nested inside the unibody frame a - dont they overheat? b - when they go bad, doesn't it make it really difficult (costly) to fix? c - on numerous occasions over the years my MBP has just totally frozen.. and the only way to rectify has been to take the battery out, put it back in, and start up afresh. How the hell do you solve freeze ups on the new ones?
