Gear4's Pocket Loops keyboard (we also saw their Unity Remote running at CES last week) represents something I think we'll see a lot more of -- devices designed to work only when paired with a smartphone or tablet device. iPhones and iPads are leading the way into a new era of mobile devices, and I think more and more toys and products will do what the Pocket Loops keyboard does: offload the heavy lifting of processing to a mobile device, and instead focus on bringing an interface into play.
As you can see above, the keyboard has a dock that the iPhone or iPod touch can plug right into, and from there, works with a free app that will be released in about three months
