My daughter still uses her 2010 MacBook (the last of the white unibodies). It is in the stock configuration and has a 2.4 Core2Duo processor, 2gb RAM and 250gb HDD. She only uses about 30gb of space on the drive. I'd like to get her a little more speed for a modest cost and have decided on 2 options. A.) Get her a SSD drive. 64gb would do for sure, but the 128gb units are a good value right now. B.) Sell the 2010 MacBook and get her a 2011 11" base MacBook Air. I figure that swap would cost me about the same bump as the SSD drive. I think the smaller display is no issue and the MBA is more portable. Faster processor, same RAM, but only 64gb storage. I think that amount is still ok for her, but of course I'd be locked in. Of these two, and only these two, which is better...A or B?
