I found this article quite interesting,
but very unconvincing on one point.
The author says 
"Since leakage from these ovens 
makes the radio spectrum near 2.45GHz unusable for communications,
the frequency was chosen in part because it would not interfere 
with existing communication systems."

Both DECT phones and GSM phones use this frequency range
without apparent interference from microwave ovens.
I've never noticed any interference with WiFi from these ovens.

I've certainly always understood that 2.4GHz was alloted to ISM
because it was unsuitable for long-range wireless communication
on account of some interaction with something in the atmosphere.
