There are quite a few disadvantages to the MacBook Air. Quite frankly, I can't see any advantage in owning one over a MacBook Pro unless portability and size are of utmost importance. Among the disadvantages are:
1. The slowest Mac in Apple's current line-up. This includes the Mac Mini.
2. Non-upgradeable RAM (you are stuck with 2GB for the life of the machine).
3. Smallest hard drive in the Mac line-up at 80GB or 64GB SSD. Upgrading will not be easy either as it requires a fairly obscure form-factor. Also, if it fails, finding a replacement may be very difficult out of warranty.
4. Non-user-replaceable battery. You must take it into an Apple store for replacement.
5. Lack of ports - there is a single USB port for any external devices. This means hooking up an external hard drive for backups will limit you to very slow transfer speeds.
These might not be a huge deal for a lot of people, but if this is your primary computer, it can be very limiting. If you don't travel very frequently, I can't see the appeal of this model other than as a fashion statement.
