Hi guys, My flatmate wants to sell his laptop sometime in the near future, which neatly coincides with my desire to buy one. It's a 2.16 ghz Core Duo 15' Macbook Pro with a 256mb ATI x1600 graphics card and 2GB of RAM. What I want to know from you guys is if this laptop is worth buying. My concerns about it are: 1. The processor is 32 bit only - which could present problems down the line as more applications are written for 64 bit. 2. The RAM is non-expandable from 2GB. This amount, while adequate, is hardly generous. 3. The graphics card is not listed as being among those supported with OpenCL. 4. I've heard (just anecdotally) that the battery life on early MBPs isn't too great. Opinions from those who have actual experience with these laptops would really be appreciated. I'm in two minds over this. I've used it (albeit for about five minutes) and found it to be a decent enough machine; solidly built with a great display. Am I correct in thinking in that the potential flaws I mentioned would possibly make the laptop a bit obsolete? I plan to offer him 600 for it, by the way. It'd probably be worth slightly more were it not for a bit of cosmetic damage.
