Canon' s compact, palm-sized HV10 is small enough to carry anywhere, although its vertical orientation may take some getting used to.

BlackBerry Pearl 8100

Why you need it: The newest BlackBerry is small and stylish and aimed at consumers, with a camera and an MP3 player.

Price: $200 from T-Mobile, plus voice plan and $20 a month for unlimited data, t-mobile.com/shop

RIM, maker of the ubiquitous office BlackBerry, is targeting consumers with a sleek and, dare we say, good-looking new phone and e-mail device. The 1.3-megapixel camera and music player are just so-so, and the alphanumeric keyboard is small and a bit weird (a full QWERTY keyboard model is said to be in the works), but the Pearl is a gem of a quad-band worldphone. After all, if you have to get BlackBerry thumb, at least now you can get it in style.
