This is the Asus Eee laptop. The model shown has a 7-inch LCD screen and it's running a fast booting version of Linux. Prices range from $200 to $330 and a basic model with 7-inch display and Wireless LAN capability is $230. Higher-end models will have 9-inch displays.

This is the Classmate PC from Intel. It will sell for a similar price point as the Asus Eee depending on the configuration. It's more bulky than the Asus Eee but it may be a little more durable.
Some Asus Eee models come with a pen input device that copies hand written notes in to the PC.
Notes can be written using a special pen on plain inexpensive paper. The one down side is that the Pen can't use rechargeable batteries.
The notes and drawings I put on the paper were faithfully transcribed to the computer.
