Not everyone needs a full-fledged smartphone, though there is certainly a lot of appeal to having constant access to your Facebook, Twitter, and e-mail, as well as the countless apps that Android, BlackBerry, and iPhone can bring to the table. Even so, non-smartphones can represent huge savings for people who don’t need so much functionality.

One such example is the recently unveiled Sony Ericsson txt. It may have the same look as an E-Series smartphone from Nokia, but this is “only” a feature phone. You’ll see the modest 2.6-inch QVGA display, along with the full hardware QWERTY keyboard below it.

As its name and keyboard clearly imply, the Sony Ericsson txt is being geared largely toward people who send and receive a lot of text messages. The rest of the features aren’t groundbreaking, but they’re not terribly mediocre either. There’s FM radio, Wi-Fi, a 3.2MP camera, Bluetooth, and a memory card slot.

Sony Ericsson hasn’t indicated a price for this feature phone yet, but there’s a good chance that it’ll end up on the “free with contract” offers with various carriers. Look for the Sony Ericsson txt in the third quarter of this year.
