It looks like the Google Nexus 7 tablet has become a runaway success, catching even Google and Asus off-guard. In fact, Google has suspended sales of the 16GB Nexus 7 in its Google Play store due to the massive backorder. Oddly, the cheaper $199 8GB model was the one that the masses have snapped up. Instead, the $249 model has been flying off the virtual shelves. Orders that were placed through last week will arrive on schedule, and we suspect that as soon as stock is replenished, Google will get the 16GB Nexus 7 back on sale. If you really want one of the Jelly Bean-powered 16GB tablets, there are plenty on eBay.
