Finally Decided! Got a MacBook Air 11.6".
After three visits to the Apple Store and two canceled online orders, I finally picked up my MacBook Air 11.6/1.6GHz/4GB/128GB.
I had originally ordered the 13/2.13/4/256, but thought that would overlap too much with my 17" MacBook Pro 2.53 (early 2009). I really wasn't looking to replace the MacBook Pro, so I cancelled the order. I also have an older 15" MacBook Pro (late 2006) that I use mostly as a MS Remote Desktop client connected to a 27" Dell u2711.
Then I ordered the base 11.6/1.4/2/64, but canceled that order. I thought I would future-proof myself, or at least extend the life of the MacBook Air by going for the "ultimate". So I dropped by the Deer Park, IL Apple Store and picked up the ultimate 11.6.
So far, I've reinstalled Mac OS X (removed languages), reinstalled iLife (only wanted iPhoto and iMovie). I installed a few basic utilities and apps including DropBox, Remote Desktop, Twitterific, and Xcode.
The 11" inch really sings to me. I've owned most of the small Apple notebooks, including a PowerBook 100, 2400c, and two 12" G4's. This 11" is really the successor and so much more. So light and portable. I'm not a frequent traveler, but I like to use my computer around the house. Lugging the 17" really wasn't that much fun in spite of just moving between floors. Now it can stay at my desk.
