I bought the $1599 model of the MacBook Air from Amazon with the 20% off coupon. At $1240, I feel it was too good of an offer to pass up. My problem is that I always research purchases before buying them. Before I bought my 17" MacBook Pro, I researched it's capabilities and limitations for at least 6 months to determine if it was the right computer for me. I am in an all digital high school, where everyone is required to have either a laptop or a tablet. I really enjoy using my 17" MacBook Pro(from 2009), so this computer will probably be only for school. I will use it for: -A lot of typing for English(I am taking a college English Class while in high school) papers that are each about 10-20 pages long. I heard the MacBook Air keyboard doesn't have as much travel as the MacBook Pro. How noticeable has this been for you? Should I carry an external keyboard around? -Taking notes. -Holding my iTunes Audiobook Library, as my teacher's often want to borrow these from me. -Reading PDF textbooks. This one is new. What is the best app for this function? I know about Preview for Mac, and will probably use it. But is there a better application for PDF textbooks? -Giving Keynote presentations. Only two questions here. Is the graphics card good enough for the effects on a projector(my 9400m card sometimes has trouble with this), and will my Mini DisplayPort to VGA adaptor work, or do I need to buy a separate ThunderBolt one? I'm pretty sure the MacBook Air will be able to hold its own on all of these tasks, but I just want to make sure. Another concern is screen real estate and quality. Has anyone gone from a 17" MacBook Pro to a 13" MacBook Air and regretted it? Also, I really love the quality of my 17" display; will the MacBook Air match it as far as clarity and color reproduction go? Any tips on keeping my two computers in sync? Thanks for answering these questions! PS: In what sleeve do you carry your MacBook Air?
