First of all - the alarm isnt work every time. It seems to ring when it wants :) I make the settings for example for 700 am, the alarm start to ring at 800, or event dont start to try ringing and wake me up. I tried several different hours, one time the alarm is working, the other time isnt.Cant fix that
The second problem is that XBOX games hub isnt working at all. it gave me only error with the update and so on .
Some of the apps dont work correctly, but tis is normal, i will wait some lite updates and fixes.
But those two problems are huge for me.
