Our sister label WhitneyApps (awww, who am I kidding, they’re both my wife and me 🙂 has posted the first part of an article about the differences between the various under $300 Android-based tablets out there right now.  You can read it at http://www.whitneyapps.com/battle-of-the-tablets-nexus-7-nook-hd-kindle-fire-hd-part-1
We hope it’s helpful.  Our apps will run on all of these devices so you don’t have to worry about that 🙂  Please leave a comment with your questions for next time or your personal experience with these devices so everyone can benefit!
Blessings,
Steve Whitney
