So lots of people are asking themselves: what should I buy, the MBP or the MBA? Do I really need a more powerful MBP or the MBA is enough? I can assure you people that the answer is REALLY simple and comes down to two questions: 1. Are you a professional? (Artist, Developer etc...) 2. Do you play video games? If only of the first answer is "Yes" then choose any of the Macbook Pro. If the answer to both or only the second question is "Yes", then choose at least the 15" Macbook Pro. If the answer are both "No", then take the MBA. Why? The Macbook Air is almost as useful and efficient as the the 13" Macbook Pro, trust me there's no differences, for the everyday use of the vast majority of users, and you get a thinner and lighter laptop. UNLESS you use your computer for processing intensive task with professional softwares such as Photoshop, Ableton Live or else, in which case you better have Macbook Pro with a better processor. AND if you plan on really playing video games, and I'm not just talking about recent ones but even 3 or 4 years older games, you absolutely need a Macbook Pro that comes with the AMD Radeon, because otherwise you wont be able to play much, trust me.
