HTC Mini: a small Bluetooth dumb phone to better use big-ass smartphones. HTC has officially lost its mind. If you think, as HTC apparently does, that a 5 inch screen on a smartphone is too big, do we have a "non-phone" for you. You can buy an HTC Mini, which will allow you to make calls on your big, honking smartphone from a tiny device that looks like a, well, small smart phone. Except that this is one dumb phone, since it tethers to the big one. I have no problem with tiny devices that connect to phones via bluetooth, like my Sony SmartWatch, or some of the small watches that are coming, and which strap to your wrist or attach to your clothing. The HTC Mini, however, is one of the dumbest ideas HTC has had in a while. And, I thought the company was coming back. Oh well.
