If you've been looking to get into the Android-based e-reader game but haven't been to crazy about the price, you're starting to run out of excuses. The Barnes & Noble Nook line just got a refresh, with a Wifi-only version going for $150, and the 3G/Wifi original down to $199. Same e-ink reader display coupled with a bottom color panel, same book library. And a much lower price.
