This past week, Barnes and Noble put the Google Play store on its Nook HD and Nook HD+ tablets. So while they’re still running a forked Android, they’ll run most Android apps without you having to do anything special. That, plus the high-resolution screen, the low price, plus the ability to plug microSD cards into it, plus the ready availability at major retailers makes for a much more compelling tablet.
Sales have been abysmal lately, but I expect this to change that pretty quickly. Now the Nook tablets have three things the Kindle Fires lack: a better screen, greater openness, and expandability. Now they look like a very good general purpose tablet, to my eye.
