Dubbed the Keyboard Buddy, this keyboard case will pair with your iPhone via Bluetooth 2.0 and will be powered by its own battery, which apparently will last you up to two weeks on a single charge – pretty impressive we have to admit. The battery is rechargeable via micro USB and will set you back $90. Previously keyboard cases tend to add quite a bit of bulk to the iPhone, but given that the iPhone 5 is not only lighter and thinner, perhaps adding the Keyboard Buddy to the mix might not be as obtrusive as you might think.
