I just got a 32GB Surface 2 and have been enjoying it for the most part. However, it seems to be getting really warm in the back (right side in landscape mode). I have all the updates installed and the screen does not dim (an old I issue I read about). This seems to be happening only when I use IE11 for a while. Almost too hot to hold. Is this common or should I exchange it while I still can? Thanks for any advice.
