Just arrived an hour ago and I am blown away so far!! Amazing! Loving this device so far. First observation is that it does get pretty warm quickly. I'm connected to WiFi only and have been using the phone for only 15-20min on web and playing around with photosphere and the phone is warmer than my iPhone 4 during normal use. Most times I will only experience this type of warmth on my iPhone if I'm using it in an area with poor WiFi or if I've been on it for several hours non-stop. Hope its nothing. We'll see. I'll play around with it some more and see how it goes.
