This QWERTY Keyboard Case concept from designer Altamash Jiwani looks like a winner for iPhone users. The case slips over the iPhone and connects to its dock port, and thanks to the iPhone 4’s new external accessory interface, it would disable the on-screen keyboard and let you use the QWERTY physical layout.
Currently it’s a concept, but this is a feature that would most definitely drive more iPhone sales. There are thousands who turn iPhone away soley due to no physical keyboard. Why do you think BlackBerry still manufactures many models with physical keyboards? Because there’s a huge market who still like the tactile feel of punching buttons. I know I do.
