4-5 megapixel is overkill for web stuff, no?
IMHO, (and you're going to hate hearing this) you really need two different cameras.
Since you know it, we'll use my E100-RS as a baseline for an action camera and the S50 as a baseline for a still camera. The S50 will be awesome for still pics like at the auto show and other normal stuff; with 5mp you can blow up stuff big time for printing. The 3x zoom is adequate for those type shots too, especially considering the versatile size of the unit. At 4.5" long and ~1.5" wide that baby will fit darn near anywhere. But a max shutter speed of 1/1500sec and lack of zoom makes action shots pretty tough. The E100 has a shutter speed of 1/10,000sec and a 10x zoom so action shots are it's bread and butter. With only 1.5mp you won't be enlarging many prints however. Oh, and pocket portability isn't happening either.
I know you're pretty specific and picky (who here isn't!) so I'd get a camera that's great for stills and englargements and later on get one for action shots. (What's your film camera again?) You will never regret buying a small, highly portable, and capable digital camera; I very much need one too.
