Hello, I'm buying a macbook and I have to choose between the macbook air and the macbook pro. I'm not a publicist nor I work with video, so I don't really need the power of a pro, but it comes handy some times and, if you can have the power stacked up there waiting for you, why not? A pretty important factor to me is how much it heats. I like using notebooks in bed on my legs and sitting in a couch on my lap. My mom has a pretty old white macbook (from the time when there where black ones) and it heats like crazy. I really disliked that and I don't want it to happen to my new laptop. ¿How much does the most basic 13 in macbook pro? ¿And with an SSD drive? ¿How much compared to a mba? The second thing that bothered me, why does a macbook pro come with an integrated grafics card! is there any way to upgrade it? Is it better to order the mbp with a factory-installed SSD or just to get the normal one and get a 3rd party SSD? Best regards!
