I've been tempted to buy a nexus 7 for my kids for a while, but at the same time I've been reluctant for several reasons. Since the XO seems to come installed with many productivity apps I may look at it instead. Not to mention that it looks a bit more durable compared to the nexus. All that said, I wonder how quickly it will be available outside the US. Walmart.com doesn't ship to canada on many items.
