A lot of it is psychology. When I hear someone ragging the iPad because it's thicker and heavier I just scratch my head. Honestly how many people can tell it's the tiniest bit thicker and heavier. If they weren't given the size and weight specifications would they even notice it?
Uh this is probably real stupid of me to post in a thread where everyone has gone completely nuts but uuhhmm there really is a difference in weight and thickness. I'm just a girl and I use to be able to hold the iPad 2 for quite along period of time with just one hand but the new one becomes heavy real quick. Not saying there is anything wrong with that as I'll take the speed, heat, weight, thickness and that bitchin screen any day over the old one. Saying you can't notice it though is kind of reaching a little, there is an obvious difference and it isn't as suttle as you make it out to be.
