My Nexus 10 developed a terrible lag problem, so I purchased the Tablet Z as a possible replacement. Don't believe the reviewer hype about the Tablet Z. It's light and that's great, but the low res screen is a deal killer. Luckily, I was able to get my Nexus 10 back working. Nearly a year old, the Nexus 10 is a nicer tablet at a lower price. I also much prefer the Nexus 10's ergonomic shape to the Tablet Z's sharp edges. The Tablet Z reminded me a bit of an Apple product - it was clearly designed with a concern of form over function.
