PointUI, a custom user interface for Windows Mobile has been chosen by Bell Canada as the base for their Bell User Interface on the HTC Touch Diamond. That means new Diamonds bought on the Bell Canada network will be even more pleasing to the eye (and finger!). PointUI's interface was also recently demoed by Telstra and Microsoft in Australia recently, it would appear that te user intrface is FINALLY becoming an important aspect of WIndows Mobile.
