This is the way the Japanese-driven consumer electronics business has always run since the early days of Hi-Fi equipment: start with a relatively simple but well-defined product, and when the steam runs out on that add bells and whistles and convince the public that they need them so much they should give up their old one.
This wouldn't be fair to apply to
digital cameras in general. As well as bells and whistles being added, the fundamentals of the technology - including sensors and processing power - has genuinely improved, and will continue to genuinely improve.
Film cameras, on the other hand, continued to have bells and whistles added after the fundamentals had matured.
Get a Pentax P30 if you want a good, simple and convenient film camera for peanuts.
