The RIM BlackBerry 7230 ($399.99), from T-Mobile USA, is a fairly small and sleek-looking device dedicated to mobile mail: E-mail meets the pager. Its menus are very easy to navigate, thanks partly to the color screen, and the keyboard layout—the best here—is very comfortable.

E-mail is stored on the server (to a 50MB limit), and each message is pushed to the device on arrival. The device comes with its own e-mail address, though you can set it up to access your POP3, IMAP, and even Exchange and Notes servers. When replying to e-mails, though, you are allowed to use only one e-mail alias, and you should be aware that although you can choose your corporate e-mail, messages won't be going through your corporate server when they're sent. The service also comes with a junk filter, which you can set to keep possible junk mail on the server instead of having it sent to your device.
