I absolutely love my 2010 13" air. I'm an information systems student at a very competitive business school and it's been a dream computer. My group consists of 4 students, 2 of which use PC's and the other has a macbook pro.
It's been amazing to see how many random problems the PC owners have had with their laptops, creating hours of issues (visio crashing, netbeans issues, android sdk issues, dim screens, bad battery, etc.)
I'm usually on campus from 7am til midnight everyday and having a portable, rock stable laptop is huge. I have a desktop at home that I built, but ever since school started I have hardly touched it. Couldn't ask for a better laptop. Hope this trusty thing lasts me for several more years.
When do I get home, I usually hook it up to my TV and watch episodes w/ my wife =d
P.S. I found it interesting that out of the program's 105 students, about 50% use apple laptops.
