Bought the X, waited two weeks got a defective unit.
Ordered Replacement, waited two weeks... got a good unit.
Used my X for about 3 weeks...
It was stolen today.... 
Contacted Asurion.. I should have my replacement X by 9/8. 
I bet everyone thought that this would be one of those, "I hate this device..." blah blah blah posts. I am genuinely saddened by my X being stolen today and cannot wait to get my replacement later this week.
