i had planned on getting a P3P, and today my wife surprised me and told me to go ahead and get the P4 if I wanted to - so of course I did. Now I'm second guessing myself and wondering if I should have stayed with the P3P. I've been trying to watch comparisons and reviews, but I can't convince myself either way. That extra $400 (or more) would put a new iPad mini with it along with a case, batteries, etc. Did I screw up? I'd imagine it can be returned/exchanged - it came from a local big box store.
