What is the difference?

What is the difference between the s and the sd
as in the s400 and sd400??
:confused:

the sd series are the only canons that use secure digital flash memory rather than compact flash... but that's not the only difference. I know with the sd500 vs the s500 they are just completely different cameras, different shape, different sized lcds, different resolutions, different size batteries...
