IPad 2 32 nm or 45 nm processor?
I think this website answer the question. you have to went a utility call geekbench or linpack
What is the iPad 2 processor speed?
Should I you get an iPad 2 or iPad 3 I like the iPad 2 costs less and is thinner but I also like the iPad 3s retina display and camera?
I suggest to buy an iPad 3 as its camera rocks,it's good resolution screen. So fast processor .ipad2 is not at all good.
How can you verify that you have an iPad 2 and not an iPad 1 since it does not say 2 anywhere on the receipt box or iPad?
The iPad 2 is slimmer and has a camera. On the menu of the iPad 2 it should have extra icons like FaceTime, Photo Booth and Camera.
