MS developer network

This preview is bugridden as h*ll. So many issues it's not even funny.
Just a few;
- WiFi OFF toggle goes to settings
- games show up in applist
- xbox (games) hub keeps reloading
- Facebook implementation is completely broken and horrible now.
- Issues with people hub, music hub, video hub
- generally laggyness
- many apps are very jumpy
Overall this is not even close to finished and not near as polished as the GDR3 update was. and I sure hope MSFT gets it together. Overall while there is some good stuff they have sacrificed way too much of the stuff that made WP what it was and it's now looking
more like Android with Live Tiles really..
Not what I bought in for..
