HTC has been constantly pushing the limits of Windows Mobile device and their latest product on the market, HTC S710 (Vox), is a good example of this effort. Besides an otherwise ordinary set of features, it boasts the latest version of the operating system, Windows Mobile 6 Standard, and – most importantly – it is perhaps the first ever device to have two integrated keyboards. One is a phone-like keypad, the other is a slide-out keyboard suitable for typing larger chunks of text.
