Hi, I have never really had a great desire to get an iPad, except perhaps for Artrage. I'm teaching a class in art rage, and at this time everyone uses laptops and the full version, but I'd like to try the iPad version, so I'm looking for a used Ipad. I see OS6 is required for art rage, but which older iPads are capable of being updated to OS6, and do the older generation iPads have difficulty with art rage? What are your recommendations for the least expensive Ipad that will handle art rage.

Thanks, Elaine
