The mobile phone manufacturers are so busy competing against each other that they very well might be missing competitors coming from the side. Like for example full blown PCs that fit in your jacket pocket such as the Willcom D4 by Sharp. Based on the Intel Atom platform, the size (188x84x25.9mm) is not that much larger than a Playstation Portable (170x74x23 mm) or a Nokia N800 (144x75x13 mm) but it’s actually a PC running Windows Vista and a full QWERTY keyboard.

The smartphone of the future is a PC. Let’s call it mobile web tablet.
