Pros:
- Extremely thin
- backlit keyboard
- multi-touch touchpad
- slightly above average battery life (for an ultraportable)
What else does it have going for it besides that? Everything else it has should be a given for something built for the ultraportable niche. At 3 pounds, it's actually on the heavy side for an ultraportable (which is traditionally classified by weight, not screen size).
Major Cons:
- 1 USB port (seriously?)
- battery not user replaceable
- no WWAN (not very portable)
Minor Cons:
- only 80GB hard drive, 64GB SSD at additional $999
- soldered-on, non-upgradeable RAM
- no Firewire
- no eSATA
- no microphone port
- Mono speaker (under keyboard)
Almost all of these cons could have been easily addressed and most ultraportable products have these features. The lack of an optical drive isn't a con for an ultraportable. How can you call it the Macbook Air and leave out WWAN?
This thing just seems like a huge toy/gimmick. Not to mention the $1,799 price tag, which is ridiculous for what little you get. Considering the hardware you're (not) getting, I'd say $1,000 would have been more reasonable.
