Just a quick post showing the size of the Canon S90 compared to my previous smallest (most pocketable) camera, the 35mm film Ricoh GR1:

Now, how about a quick comparison with the 5 megapixel Canon Powershot S60, which I also own:

The S90 is clearly thinner and more pocketable than its predecessor, the S60.

The S90 turns out to be *very* similar in thickness/depth to the Ricoh GR1 (35mm film camera…which fits nicely into a front jean pocket, for example); but it’s quite a bit smaller in the width and (especially) length dimension versus the GR1.

All in all, I’d say the S90 is clearly the most pocketable. Now, how “usable” is such a small digital camera? More on that later…
