My wife finally got one. It is really nice but the on-screen keyboard is awful, I have to test some other solutions like Swipe.

The configuration of the Wifi is quite painful compared to Maemo, and I have to manually change between static and dynamic IP.

There are thousands of useless applications that threaten your privacy. Most of the rest doesn't work without Internet connection, but still there are some nice and useful applications (most of them with open source alternatives in Maemo Extras).

The transitions and general feeling of the UI is awesome. Phone capabilities are beyond N900's, and the magnet is incredible useful for geolocation and augmented reality applications.
