Over the past six months or so, Asus, Everex, and HP have managed to bring low-cost ultraportable notebooks to market.

Some will have flash memory, while others will have hard drives. But every one will be smaller, lighter, and cheaper than most existing laptop computers. Here's a roundup of some of the computers that have been announced or are already available.
