If there's one gripe I hear about the iPhone, it's that it doesn't have a "real keyboard." Sure, you can tap with one or two fingers (or thumbs) pretty quickly on the virtual keyboard, but it just doesn't have that nice tactile feedback that you get with, say, a BlackBerry keyboard.
Mobile Mechatronics, the same people who are bringing you the Blur Tripod mentioned on TUAW earlier today, will be officially announcing their iTwinge snap-on keyboard for the iPhone tomorrow. This is a cool little unit, at a price of US$29.99, that is likely to be very popular with the BlackBerry set. The iTwinge snaps onto the bottom of the iPhone, then allows you to use the keyboard for thumb or finger typing into any iPhone app that would normally use the virtual keyboard.
While you wouldn't want to keep the keyboard attached to your iPhone all the time -- it covers up almost half of the screen -- it would be perfect for those situations where you aren't near a laptop or desktop computer but still want to be productive. I'd love to have one of these to use with our blogging system so I could blog and edit from anywhere.
Mobile Mechatronics has begun taking pre-orders for the iTwinge, with shipping expected to begin on November 19th. I just wonder if the name has something to do with carpal tunnel syndrome or "BlackBerry Thumb" that you can get from overusing thumb keyboards...
