Amen! Unfortunately this forum is a magnet for techno-geek oneupmanship...
My wife has the 3 and has no complaints whatsoever.
I love my 3 but I do know the 4 is quite fast in comparison. It still never made me jump on buying a 4. In fact, I would like to "retire" my 3 to the kitchen as I sold my kitchen iPad (iPad 1) months ago, and grab a mini for everyday use. The retina and larger screen is perfect for me in the kitchen.
