[iBook] iBook feels very hot now with Airport usage

[Michelle]

Hi again,

Since going "wireless" a couple days ago (w/Airport Base Station 
"Graphite") with my iBook G4 14", I have noticed a definite change in 
temperature, on the left half of the machine (on the bottom.) Whether 
on my lap (which isn't often since it's so hot and I am wearing 
shorts) or on the desk... it is noticeably HOTTER than it ever was 
before, even when I had used energy-hog things like PhotoShop, 
iTunes, etc...

Does the Airport card and/or base station usage cause the iBook to 
run or feel this much hotter?

Is there anything I should do about it, other than consider one of 
these "cooling" type gadgets (lap-pads), etc?

Thanks,
Michelle
