I'm about to buy a baseline 13 inch MacBook air And I was wondering if the stock 128gb ssd would be enough or if I should invest in a third party ssd, like maybe a 512 one. I am going to register as an apple iOS developer and put Xcode on this computer. It will be my main computer until I get enough for the Mac pro tower I want. And don't tell me I should just get an iMac or something for 1199 because I've already decided on the air. And help is appreciated
