Is Your iPad Running Hot ?

So I know that Josh said that the LTE iPad runs hot after a while of using it on cellular.

I got the new iPad upgrading from the original iPad 1, I have the wifi only version, and I can feel it getting warm after short time of usage (20-30 minutes)

I am a little bit annoyed about this, I don't know if all of you are facing the same issue, or is it just me ? I never faced this in my iPad 1, I guess for the fact it has a single core processor and an extra space to breath inside.
