Well, you guys probably have seen many of these type threads of a similar dilemma. By using the search tool a bit, I have found this thread: http://forums.macrumors.com/showthread.php?t=586937 and it's quite helpful and answered many questions, but I still have a few. (As this will be my first mac purchase, except my iphone, so kind of a Mac noobie, sorry .) My budget is around $1500 (educational discount can apply for me) and I really just want a solid laptop for the typical internet/photos/music/movies and a few games here and there. The 2.4ghz model is $1499, so I will be unable to upgrade it any until a later date (until my wallet can). But the 2ghz version I could stick 4gb of ram, and a better harddrive for around $1450, saving $50, but not have that .4ghz. I really don't need the illuminated keyboard, I can type quite well without looking down, but I also don't use my laptop much in the dark either. But, when upgrading the laptop myself (Buying the (2x2gb) sticks and a bigger harddrive from newegg) does that conflict with the warranty/service any? Would they not service it because it does have a different harddrive and ram? Or would Apple hopefully not mind? If they don't mind, then would 4gb ram/better harddrive really be that big of a boost? I plan to run Fusion (XP or Vista) for a few things, so the 4gb should help with the visualization. Also, if I was to get a bigger/faster harddrive as well, would a 7200rpm harddrive affect the battery life? Thanks.
