I got a Wi-Fi model on launch day, but my LTE model came last night. I am not certain yet which to keep and which goes to family. One thing that immediately struck me was the weight of the 64GB LTE compared to the 32GB WiFi. No, I would not recommend anyone make a decision based on weight. Nevertheless, after using the WiFi model for a few days, I must say, you DO notice the difference. The LTE in particular feels more top heavy, which can make it feel a bit odd while reading. I suppose someone extremely weak or elderly MIGHT benefit from the lighter Wi-Fi model? I believe you notice it so much because of the top heavy feel it (LTE) gives to it.
