Went today to try the two new iPads, but the 4 wasn't there although I've tried numerous times the 3 so I now how the screen looks, the weight, the speed, etc. So I played with the mini for 20 minutes or so. I must admit I had no desire to buy it when it was announced, but after trying it I'm undecided. The size and weight is a huge advantage, as so is the screen of the 4. I read a lot of PDFs on the iPad so the bigger screen is better but the size and weight can get annoying. My PDFs are only text, so I tried zooming on the mini and it look good, not great, but good. I know the biggest and better jump would be to the 4, but the size and weight of the mini made it so so comfortable to hold that my hands didn't felt tired after 20 minutes. Just after that I held the 3 and wow, like 3 times heavier. Advice?
