WMPU has just put up this great little look at the calendar app that’s going to ship with WP7. I must admit, that looks damned good! Multiple calendar sources, slick interface, the ability to link it to people or places, all great features. I think this is also the first real look we’ve had at the date and time pickers, which put a uniquely WP7 spin on setting your time.
The more I see of it, the more I’m impressed with what Microsoft is doing with the WP7 UI. It looks incredibly polished and fast, even using both beta hardware and software.
