PocketCM Keyboard is a drop-in replacedment for the standard on-screen keyboard on Windows Mobile. Apart from the "iPhone-esque" revealing of letters as you press the screen, it has a some neat dictionary and auto-correction features, full keyboard customisation (even down to the individual images displayed on keys), a "keypad" type feature where if you hold down a key for 250ms a new selection of keys will pop up (such as a number pad or row of symbols), and a whole lot more... And it looks quite usable too! I wonder if Microsoft will catch on, or just be happy to watch the community build third party tools.... Personally, I'm happy with transcribing (hand-writing recognition) and a physical keyboard, but this could add another edge to the already versatile Windows Mobile products :)
