Not my experience... Cannot remember having a freeze or random reboot on this tablet. But I hear you! Sounds as if you got a lemon (or two!).
Are you on the .29 firmware? The latest update? That took care of the battery drain...
In your shoes I would factory reset it, manually flash the latest firmware and if it still does it - back it goes!
I also have this intermittent problem where it won't charge until I use a friends tf700 charger (my cable). Once I plug the other one in, mine starts working again.
I'm on the latest firmware and it's an identical issue to my last one. I think I'll send this one back to Asus instead of the shop because they'll just keep giving me the same batch. (2014.01)
