I saw this advantages:
-It keeps you informed about how many BTC have you got and the conversion between USD and BTC.
-It doesn't log you off when you click on the main page (in BlockChain.info it happens I hate that).
-You can earn BTC and have referees to earn some cash.
-Cool design in red.
Disadvantages:
-It just has 2 translations (English and German).
-You can't import private keys from another address.
Looking good no? I sent all my money to that wallet. Let's see if they don't steal my BTC :P
