iPhone and iPod Touch owners rejoice that a physical keyboard is finally coming out for your favorite device … but try to keep yourself in check until you learn the details.

Ion, a company best known for its USB devices, has announced at the Consumer Electronics Show (CES) that it is releasing a physical keyboard for the iPhone and iPod Touch, something users have been longing for since both devices first came to market.  Called the iType, the device will allow you to snap your Apple product into the top of the device and type on a nearly full-size physical keyboard while your device is in landscape mode.

While this sounds exciting at first, and you may have images of catching up on your emails dancing in your head, the keyboard will only work while you’re in the iType application.  You will then have to copy anything you write there and then paste it into the application you want to use it in.  A definite nuisance, and one that makes you wonder if the product will be worth it once it’s released.  No price has yet been announced which makes us even more suspicious that it is just not going to be worth the investment for being so limited in scope.
