I haven't switched yet as well but that does not mean that I am surprised. I was expecting some of the problem (like the lack of LPM, pebble not working...)
Some were almost surprises like the fact that I cannot get mfe to read my google calendar (probably related to Google preventing it from working properly now)
I am waiting for Gpodder as well as I am a great user of it with N9.
And there is a couple of issues here and there.

But at the end, I still have it opened, I am using it because in some activities, it is way faster than with N9. I am using it because it is cool. And I am looking forward for the coming developments (the phone has been in the market for 3 weeks now) and the community to take its part in the development of nice app around the OS.
