I'm unhappy that my iPad 1 is essential on it's way to brickdom.
I had bought it planning to pass it on to my toddlers as it reached about 4-5 years old.
Unfortunately I don't think there will be any supported iOS 5 apps at that point.
I may have to jailbreak it just to get a newer version of the OS on it at some point (assuming that someone gets the newer OS working on it).
