This is a beautiful piece of work you've made. I'm partial to the 2x2 with a logo so please let me know when you have some available as I will purchase one directly from you.
Also, have you thought about making a replacement rear for the 1st gen iPad? Lots of people complaining about the weight and since you have such a talent for these items you'd have a guaranteed market for the iPad. I'd certainly buy one, or order a custom one if you'd be interested.
