LG and AT&T announced the LG Invision handset yesterday, a mobile TV-equipped phone that is being heralded as the smallest mobile television-capable product on the market. The Invision, aside from its TV capabilities, is a pretty run of the mill affair, sporting a 1.3 megapixel camera, Bluetooth, 3G (of course), and little else. Viewing TV on its diminutive screen doesn’t’ sound terribly appealing to us, but if the prospect of a 4″ tall x 2″ wide mobile television in your pocket is too appealing to pass up, you can pick one up for $99 after a $50 mail-in rebate. Not too shabby, but not exactly our cup of tea either. For our money, we’ll stick to a SlingBox coupled with a screen big enough to see what we’re watching.
