Toshiba is best known for its laptops, but it also markets handheld computers. The latest is the e350 Pocket PC, which is just 12.4mm thick and weighs in at less than 150g. This palmtop has a colour screen, and for extra data storage, it uses Secure Digital (SD) memory cards, which are about the same size as a postage stamp. Use an SD card and the e350 becomes a video player or personal digital photo album. There is also an option for using a wireless Bluetooth card with the laptop.
