We already have a 16gb iPad 1 3G, a 32 gb wifi iPad 2, and now I can't decide which to keep for my new one. Would you keep the 16gb Verizon or 32 gb Verizon? I will get 4g service and plan to stream most of my viewing media. I have never put music on my iPads bc I have it on my iPhone. Could I really fill up an iPad with a full 16 gb with apps? Will the retina apps really be that much bigger? The other two iPads are my kids and I'm hoping to keep mine for me and theirs for them.
