As a complete package, the Titan is easily one of my favorite Windows Phone to date. The build is phenomenal and the Windows Phone 7.5 operating system is like greased lightning. I'm also a huge fan of live tiles.
Microsoft's home screen UI, for those unfamiliar with Windows Phone, is tile-based. It features a grid of square and rectangular tiles that cascade endlessly. The result is a tidy home base that offers a welcome alternative to static icons. These tiles, if enabled, provide the user with information dynamically and can be updated frequently.
For example, my favorite simple weather app, WeatherLive, displays the current temperature, the temperature range for the day, and a graphical representation of the current weather conditions. When it rains, I see a storm cloud and rain drops. When it's sunny, a big sharp sun covers the bulk of the tile.
Another example is my favorite Google Reader-compatible RSS Reader, Wonder Reader. When enabled, the app periodically flashes headlines across the tile to let me know I have new articles waiting to be read. Messaging apps display unread counts, the Photo Hub cycles through images stored on the device, my Xbox Live avatar dances around the Games tile, and so on.
