I have decided to get my first mac and up until yesterday I was pretty set on getting a MBA 13. The revelation that came to me yesterday was when I went to a store and tried typing on both the MBA and the MBP. For me personally, the MBP keyboard felt a lot better. What I would like to get more input on is experience on writing extended periods of time on the MBP 13. I have been to stores and tried it out, but I couldn't really sit there for several hours and just type. I read the following in a review (http://www.notebookcheck.net/Review-Apple-MacBook-Pro-13-2010-04-2-66-GHz-Notebook.33236.0.html): A further point of criticism levied on the previous unibody-models remains the same: the sharp front angle is uncomfortable to the underarm after periods of long use at a desk. I can't really understand that, but on the other hand I just typed for 15 minutes or so. So please post your experience regarding typing for longer periods of time on the MBP 13.
