I have a 32 gb 4g new iPad. I got it because apps for the new retina display can be pretty big, but I don't have that much music or movies so I thought that 64 gb would be overkill. I got 4g because I take my iPad everywhere, and it'd be annoying to not be connected unless I'm in a place that has wifi. Plus it has a free wifi hotspot included in the price (I got the Verizon one, AT&T doesn't do that)
