The us of the word "compatible" in the IT world is interesting.
As I said earlier in this debate and in other threads, SWMBO loved her ipad2.
However, time on the apple community boards and elsewhere on google shows that the ipad 2 is not "compatible" with ios 6. All the foul ups reported are not just cos the Ancient household is technologically backward.
Apple limits software updates. We've an older Touch that no longer "benefits" from software updates. That's fine by me. It does what we bought it for.
I wish they'd done that with ipad2 and ios6.
