I'm debating between a new Air or Macbook Pro as my first Mac. Right now, I use an older Thinkpad for work, but, even though it's only 14", it's kind of a chore to travel with (admittedly, much of that is TSA's fault). It also doesn't have the best battery life. I'd rather travel with something more convenient, but I don't know enough about Macs to figure out what is best. 13" pro? 11" Air? All Greek to me, even after reading around here. Uses would be general productivity--email, browsing the Internet, using Citrix to connect to work and, well, work. I might use it for music, though, when on the road, that would more likely be my iPod or iPad pulling that duty. Likewise on movies, unless I get really bored in a hotel room and want to watch something that I can't on the iPad (espn360 comes to mind). The machine might see similar use in my home (my Thinkpad is usually docked). I don't game (I have a 360 and a Wii for that), I don't edit videos, and I rarely do anything with photos that I take other than crop them. Any suggestions as to suitable machine and configuration are welcome.
