People have used the excuse "it will not be futureproof" to avoid buying the MB and instead buy the MBP. One reason why they go with the MBP is because if ever needed, it is able to be upgraded to 8gb of ram. This may be necessary in the future. According to Apple, the MB can only be upgraded to 4gb of ram, but other reports have said differently. According to macworld.com and other sites, the macbook can support up to 8gb of ram perfectly fine. The MacBook ships with 2GB, and Apple will double it to 4GB for an extra $100. Apple officially lists the maximum RAM at 4GB, but since it uses the same chipset and components as the 13-inch MacBook Pro, it does support up to 8GB as well. Of course, 4GB SO-DIMM RAM modules are still very expensive. OWC offers an 8GB upgrade kit for $476, for example, but as prices drop in the next year or two, having that 8GB ceiling as an upgrade option will be a good thing. (Apple doesn't offer an 8GB option for the MacBook, and currently charges $700 to upgrade the MacBook Pro from 2GB to 8GB.) http://www.macworld.com/article/143511/2009/10/unibody_macbook_review.html My point is is that the macbook offers the same specs as a low end macbook pro...but people still choose the pro because it will be good for the next couple years and have upgrades to 8gb if needed. apparently u can on the macbook too. what do you think?
