‘ve been a believer since day one, and against all odds. I really think Microsoft is a real and serious player in the mobile OS war (as opposed to Palm, which despite the fact that they made a nice OS did not have the money to support it).
After playing with the latest 7.5 release, and notably with the Spotify app, I think it’s safe to say that WP7.5 is finally ready for prime time. Backgrounding works, the UI is smooth and responsive… Although the slide UI is a bit of a pain from a developer point of view (you have to rebuild/rethink your apps to match that experience) and the app store is still a bit empty because of that, I’m sure frameworks such as jquery mobile will soon support those kind of transitions.
Moreover I was surprised to see that finally the mobile IE is up to the task displaying html5/css3/js websites properly as their webkit couterparts already do.
I guess I’m going to give a close look at the Nokia Lumia tonight a the launch party!
