So far the best calendar App I have found is VsysCalender WP8. It has a few issues but overall pretty good. If MS would just make it where I could actually read the calendar I would be happy. I have a gmail account, Hotmail and Outlook. Trying to get them all to sync on a calender has been the issue with other calenders. Week Cal looks great (MS should use their month view) but not matter what I try to go into to edit it says "not editable. No windows live appointment." When making an appointment it will not let me pick which calendar I want to add it to. Since Gmail is personal, Hotmail is work and Outlook is family, when I add an appointment they all go out into the world to different areas. As for the music player, I used Win Amp on my Atrix and it was easy to navigate in. If you go to artists in Nokia and want to pick a song it takes 3 steps that you must go through in reverse order to get back to the artist list. It would be nice to have a my music button always on top that you can hit that will take you straight there. Take a look at Audio Player. It is simple and works well although I have not figured out why they use a handicap symbol for artist. And finally I would still like a continuous notification for texts and voice mail until I acknowledge it.
