Someone must have been living under a rock,
for the last 5 years, or they would have known that there was no Flash on ANY of the Apple Idevices.
One wonders if you know of any tablet that will do the things that you want and, apparently, miss so much.
As for Flash, did you know that Adobe has stopped any further development of it?
If you feel so wronged, put the thing on eBay and get whatever you want with the proceeds.
