I got an 11" MacBook Air with 128gb, 2gb, 1.4ghz. Been very satisfied with it. I just can't help thinking if a 13" would serve me better, because I use the Air as my primary home computer. Can't use my own computer at work so this is mainly at home (about 90% of the time), conferences, or vacation. On top of the Air, I got a 21.5" LED monitor, wired Apple keyboard, Magic Trackpad, and a 500gb passport hard drive. These turn my Air into a home desktop. Performance really isn't below adequate, but knowing that the 13's faster processor could speed things up is making me think twice. I'm planning to get an Android tablet (probably Galaxy Tab 10.1 or 8.9) and will have an iPad 2 in the office so this adds to my feeling that the tablet could satisfy my need for portability in some scenarios, except for events like conferences. Thoughts? I really don't know how different my experience will be if I switch to 13" _________________________ EDIT Getting an iMac seems to be the popular choice, but it doesn't seem to be for me. I'd choose Air + external display over an iMac any day, because of my needs. Don't get me wrong about plugging my Air 11 to the display, keyboard, and trackpad. I do it only whenever I'm on "work mode" or watching a movie at home on my table. It's not primarily a desktop. Half or most of the time, I use my Air without the external monitor even at home. I also bring it with me for some vacations and conferences. Found the portability very valuable. As for power, I never really found my 11 inadequate. It's very fast. Feels much faster than the i7-powered Thinkpad I'm using right now at work. Just thinking if the Air 13's performance diff and battery would outweigh the benefits of the 11.
