Is there a digital P&S out there that is as quick as a film camera?
I think so, but the price is comparable to an SLR. The only ones I've messed with that were relatively speedy were in the $500+ range.
The real problem is autofocus speed. It's a function of the necessarily smaller lenses on most P&S cameras. Less light transmission = slower focus. It gets compounded when you start upping the pixel density on an already small sensor. Higher density means smaller element. Smaller element means less surface to gather light. Less surface means less sensitivity.
They sure can come in handy, though. A pocket P&S is a heckuva lot easier to tote all day than a glassed- and flashed-up SLR.
