Twitter only device appears – sign of the apocolypse?

The Wall Street Journal | Blogs brings us the tale of the TwitterPeek. Similar to the Peek Pronto, and produced by the same company (Peek, the TwitterPeek device is available for a set price ($99.95) with a subscription (six months free, then $7.95/month) or for a one time price ($199.95) which includes “lifetime service” – as long as the service is available, I guess.
While I don’t have a problem with Twitter – I tweet quite a bit – I have to wonder if this device will take off like they’re clearly hoping that it will. If people aren’t adapting to use Twitter on their cell phones – and considering that you can simply send a text message to update it on even the most basic phone – then I wonder who their target audience is.
I myself tweet from my cell phone, the computer I happen to be using, or even my iPod touch. It’s easy, convenient, and hassle-free – so maybe they have a point here. I guess maybe my problem is that it becomes yet another device to carry around. Granted, it’s purely optional, so I guess it becomes a matter of using it or not, depending on your needs. I wish them luck, but I don’t think I’ll ever be buying on. Christmas sales, however, will be a good prediction of how the device will do over all. Time, as always, will tell all.
