I am currently sitting / lying on a very nice Christmas gift I received from my employer. This thing is a sort of sitting-bag; but then something like 10 times better 
It is filled with something that warms up very quick; and stays at a very nice temperature. It is greatly relaxing while reading some article about AJAX which is, although it is a spoof, a very nice article with definitely some good points in it to think about when developing using AJAX.
