While there has always been tension regarding how much is too much or too little, the rate of digital revolution (because they can do it) has become a juggernaut designed to separate us from our money in ever tightening cycles.
So instead of refining and improving something like the A900, we get a whole new experience whether we like it or not. Or a Sony NEX5, then 5N, then 7, then 6 ... wonder when the NEX1, 2, 3 and 4 will debut?
By the time you get something down pat so it disappears in your hands while making images, the next "mandatory" all new all singing/dancing thing barges its way into the process, and you start all over.
(Pardon me as I pull my teeth out and gum the next sentence while doing my best Walter Brennan imitation):
Why youngin, used to be you'd buy a Nikon Pro body and the next one didn't show up for 7 or 8 years. Now, just because the media changed, we have to contend with all this hoopla almost all the time.
Haven't seen a Nikon digital body the equal of the F6 yet. Haven't noticed the pictures getting any better either.
