I'm having this problem as well. Thinking about flashing a custom rom/kernel to see if it solves the problem since it's been a problem since I got the tablet months ago.
I wish the Nexus was the One X+. I don't need to carry around a damn tablet and as long as it has 2 gigs of ram and 64gb storage in the states that would be my ideal device.
News did just break that Samsung has been producing 128gb mobile chips. Maybe memory is cheap enough to take the plunge. Sounds like a good opportunity to gain an advantage against Apple.
