A lot of the smaller cameras are no longer offering them.  To be honest, given that a number of small digicams that do have viewfinders only show about 85% of the actual frame then you might question their usefulness anyway.

I can't remember the last time I used the viewfinder on my A70 but then the battery life is so good I never feel the need to conserve power by switching off the display.

You might even say that a back up battery is more useful than an optical viewfinder if power is running low.

I guess the one situation where an optical viewfinder would be useful would be if the sunlight makes viwing the display impossible.
