With a new size and lower pricing, the latest iteration of the MacBook Air makes it more of a practical choice and less of a luxury purchase. The CPUs aren't the fastest, but that's balanced out somewhat by the speedy solid-state drives. The $999 11-inch model comes with a 1.4GHz Core 2 Duo chip, 2GB of RAM, and a 64 GB SSD, but go-ahead and spend the extra $200 to double the storage. (There's also a 13-inch model for $1,299, but go small or go home.) Pick up the $80 external SuperDrive -- about the size of a CD case -- for installing software.
