It's amazing to watch the changes Microsoft's Windows Mobile team is putting together towards the release of Windows Mobile 6.5
You can actually see the new stuff while they are being created; first, it's just the functionality, not working so well, then it starts to work better, and last comes some UI tuning.
Here's a great video by PocketNow.com which presents some new stuff for Windows Mobile 6.5. It's just like watching the birth of another... iPhone-like phone, because the buttons moved down, a magnifying glass was added, and everyrthing else is just more finger friendly. Nevertheless - I like it.
