Does the Arc 7 HD have a proximity sensor?  
Picked one up as a Christmas gift for my girlfriend, but the sleep cover for the Arc is terribly cheap, not to mention overpriced.  I'd like to buy a 3rd party cover that just relies on the sensor that's in most other Android tablets.  
Thanks for a head's up on this.
EDIT:  Answered my own question.  Apparently not. 
 
  
Returning it and buying another Asus.
