IF the 10F200 is in fact 2mm x 3mm that makes it 50% larger in body
area than the 2mm x 2mm AVR.
(2.05^2 max)

And IF the PIC is 1mm thick then it is > 50% taller than the 0.6mm
(0.65mm) max AVR thickness.

I think the advertising hypers have valid grounds there :-)
Just because both are inhalation hazards doesn't make the ratios invalid.

For most things such size differences are wholly irrelevant. For some
they make a vast difference. Maybe.
I hope never to be so unlucky that such differences are relevant to
anything I do :-).
