First of all, thanks for reading. I've just got some questions, some may be easier to answer than others. From reading these forums I've gotten something of an answer for some of the questions, but am hoping for more direct answers (these MBPs are a big investment . Most of the questions are for the MB AND MBP. The latest revisions and some extra cash I just got have rekindled my hopes of affording a MBP. 1) I know the RAM is easily upgraded by yourself, but can you replace the hardrive on the MB and MBP? This especially applies for the MB, since I dont think 80 gigs is enough and I'd much rather do the upgrade myself. 2) I understand the latest upgrade to Mac OS X (Leopard) is coming out this year. I'm curious, is this a free upgrade? Or would a Tiger user need to buy the update? A windows comparison: is it a service pack or new version? 3) If I did go for the MBP, I could only really afford the base version. This leaves me with the 8600m with only 128 megs of VRAM. I'm wondering how the mac users here think it will affect my game performance (almost always running in boot camp). I'm aiming to play Age of Conan, a game that will have similar specs to Oblivion. Most of the benchmarks, if not all, I've seen have been for the 256 meg versions. Sorry if I came across a little too misinformed. This would be the first time I purchase a mac... hell, it's the first time I've ever even considered a mac.
