So I've finally saved up to get a MBP and will be getting one in the next 3 weeks, but as of late I've been torn on which model I want. Originally I wanted the current 15" 2.8Ghz since it has everything. But then I read a thread about how most people don't even use the discrete graphics card and it's more of a battery killer than anything. I will be doing some gaming and some photoshop work and maybe some video editing. So then I thought hey, I'll save myself $600 and get the 15" 2.53. I've been going back and forth on if I really want/need the discrete GPU. Then I came across the refurbs, which only added to my uncertainty. I saw the 15" 2.66 model which has the 512mb discrete with 6mb L2 cache. That's for $1700, the same as the 2.53. So it is between those two. Here is what the cost breakdown will be. 2.53 1700 - 100 (edu discount) + 90 (320gb hd @ 7200) = 1690 + free ipod 2.66 1700 + 85 (tax) = 1785 I can avoid the tax if I get the 2.53 because I can buy that in a NH store while a refurb I must buy online and have shipped. As far as I know the only difference between the models, apart from the graphics, L2, and hard drive size of course, is that the 2.53 has the 7 hour battery which is something I really want. So it's a question of battery vs performance. But do I really need the performance? Is apple working on a software change to dynamically switch between gpu's on the fly? What are your thoughts? The free ipod isn't a deal maker or breaker. It's more about the pc.
