If Droid is a do-everything handset, then TwitterPeek is the opposite: it does one thing and one thing only – access Twitter. It’s a handheld device with a QWERTY keyboard and a promised battery life of four days. Its sole purpose is to let people use Twitter on the go, paying $199 up front for the device – a price that includes lifetime unlimited service over US mobile networks with no monthly contract. It’s already being slated as a white elephant – there are plenty of Twitter apps for mobile phones, so who needs a dedicated device? That said, maybe there’s mileage for a label to buy a bunch of TwitterPeeks and distribute them to artists for on-the-road tweeting. Maybe.
