The Nook Tablet's biggest problem so far has been that it costs $50 more than Amazon's Kindle Fire while targeting the same budget-conscious Android tablet market. That's likely to change soon, however, as we've come across documentation showing a planned February 22nd launch for a Nook 8GB Tablet. It appears to be the same Android slate as Barnes & Noble's current $249 Tablet, but with less onboard storage (matching the Fire's 8GB) and what will very likely be a correspondingly lower price. All we know for sure is that Walmart plans to launch this new device at 12:01AM on Wednesday, February the 22nd, and deliveries of the 8GB Tablet should be arriving in stores already.
