Nothing like making my 7 month old iPad go from The New iPad to The Old iPad, for shame Apple, for shame. And comparing a $199 device to a $329 device was slightly sad in my opinion.
Seven months isn't exactly young in computing world. Besides, the iPad 4 really just is a spec bump of the processor. I doubt it is worthy of an upgrade. And I have the iPad 3 and use it every day.
I'm disappointed that iPad Mini doesn't have A6 processor though. I'm not sure why it doesn't except maybe cost and lack of access to those processors since the iPhone 5 is using them in huge volumes.
