Has digital camera development hit the wall?

I would much rather have a product that can do anything I need, or might sometime need, than one that fits my uses today but tomorrow says 'Oh, sorry, I can't do that.'

I've been involved with computers for about 30 years now and the early spreadsheets on some of them were convoluted, inconvenient, confusing and limited. I would much rather have today's Excel than something more restricted, because 'back when' sometimes I found myself bumping the limits and it wasn't even very hard to do.

(My least favorite spreadsheet made you go through a bunch of menu options in order to print out the sheet, but would let you close the sheet without saving it first - losing the changes or the whole sheet.)

Do people really spend $700 on a camera so they can take a picture of a squirrel or a duck?
