Thank you for the prompt reply. I will also have an iMac desktop to use along with the MBA. Did you find much of difference in the display resolution between the two??
Difference between the 13" and 11"? Yes, the 13" feels like it has much more display area and the pixel density is a bit less on the 13" so small items are easier to see. However, after a while you adapt to the 11". Turn dock auto-hiding on and the display area isn't bad. The top to bottom distance is the tightest but that is primarily because it's 16x9 instead of 16x10 on the other laptops. However HD TV shows look really good and have no letter-boxing.
I've been using Apple laptops since the PowerBook 100 (I also had a Macintosh Portable too, but let's not talk about that). While the 11" is really a future direction (16x9, SSD based, etc...) to me it also feels like a blast to the past. The early laptops weren't nearly as thin and light but they also were smaller in other dimensions compared to today's MBP. The 11" reminds me fondly of the PowerBook Duo, 1400, and 2400. It feels like a return to the laptop's origins while also reaching to the future with the high-res display, fast SSD, and battery times.
