I am interested in developing apps for iPhones and iPads. I know about Apple's Developer account and SDK. I also know that I should have a Mac to develop the apps. So, here is my question: Should I buy a Macbook Pro or a Mac Air? I don't want a desktop computer, because I live internationally and I need to be mobile. I would prefer the Air, because it is lighter and easier for travel, but I don't want to buy a laptop that won't do the job. The sole reason to buy is to support SDK. Thanks in advance for your advice.
