If you have any sense you won't even consider using the "air" as your only computer ..
Hey, I've lived on three TZs and was the first one to own one in the U.S. on June 13 and speaking from experience:
1. SSDs materially speed up use of a 1.2 computer to the point of being comparable to a 2.2 CPU.
2. I couldn't live with just a 32GB SSD, but I've learned to reduce my frequently used files size down to 30GB so I can live permanently in the MBA's 64GB space *with* an XP partition, which requires at least 5GB of space.
3. While the TZ's footprint is clearly preferable from a traveler's standpoint (I travel 40 weeks per year), I will take the MBA until Jobs recants on this strategy and will try to fly business class as much as possible.
4. The MBA is designed for a new world. Combined with Time Capsule, I will be able to wirelessly share my MBA with my archived files and the TZ, which I plan to keep.
5. As someone who has to travel with two laptops most of the time, let me tell you: *every single ounce counts.*
6. I carry a lot of stuff with me on trips as a speaker to make sure I'm "failsafe," so a 320GB Western Digital Passport is definitely part of the package, although I plan to leave the SuperDrive at home and just bring the Ethernet dongle in my suitcase.
