I agree, I think windows phone has a lot of promise. Full disclosure I have been using it since 7.0 with a Gen 1 Samsung Focus and even back then though it was in its infancy it worked well just with no bells & whistles.
Apps are coming gradually, still some major ones missing but it seems they are picking up steam.
Things I want/need: separate volume controls for media and notifications, a unified notification center for designated apps, tv remote control app for my LG LED TV or better yet universal remote control, my bank is a small place so probably not gonna get an app for that but more banking apps, instagram (not for me just so people stop bitching about it), improved Xbox music (needs work), better voice controls and a good IRC client.
All in all though I could get zero updates for my 920 as of now and be totally satisfied with the experience.
Glad you are enjoying too!!
