I'm pondering whether I should sell my Black 2.16GHz, C2D Black Macbook (2gb Ram) with a new palm rest case replaced by apple in the last week. I can get about £200 on ebay for it. Is it worth selling and buying a 13 Macbook Air i5. I need my laptop for internet browsing, Microsoft Word, Serato and non graphics intensive stuff. Is it worth using the remaining capital from the Blackbook (which I love) and transfer it to some updated horsepower of the i5 Air. I'm not too bothered about a drive.
