Why? Because they can only take one step @ a time. The 300D is more of an answer to Sony's similarly-priced fixed zoom unit.
What has kept me away from a Pentax P&S digital is one simple thing -- the lack of a dedicated flash shoe. They do a well at hitting the casual enthusiast market but no so well at the serious enthusiast market. The products are good but not excelling in the feature-rich advantage as in the past. The particular market price-point niches are still being carved out. The imaging computer market boom today is as new as the desktop computer market boom of 1988-1990. I expect by 1/1/04 we'll see a Pentax dslr @ the $250 price point with 4-6 Mp. *istD-5n. CRB
