Over heating of 13" uMBP and power pack

[gdc]

I bought a 13" uMBP pretty much as soon as they came out.
I am now noticing heat in the power pack - so hot I'm barely able to hold it once it has been plugged in for, say, 15 mins.
I also think that the battery is now getting uncomfortably warm in a way it wasn't initially, although nowhere near the temperature of the power pack.
Has anyone else experienced this or heard any reports of similar incidences?

My fried uses the HyperMac with his MBP 13" they both get noticeably warm after a while but not to the point where you can barely hold them. Something's definitely not right.

I'm not so sure this is a 'real' problem - as I've tried charging from different sockets, and avoided using the adaptor I had to use, and it didn't seem to be so hot after all.
