I do not agree, Ruben (is it just me, or is this forum being invaded by Dutchspeaking people
It's not because live view is working in a decent way that, say, an A900 would become less professional.
I think some of these P&S techniques may be valuable in everyday professional use. I can imagine that for instance live view, when used on an articulating LCD, may come in handy for photojournalists. The reason most Canon or Nikon users do not use live view, is because of the way both manufacturers implemented it: live view is considered a P&S gimmick, which is slow in use. We see that this is not necessarily true...look at Gordon's review of the A550 - it shoots at 4 frames per second in live view, which is as fast as the D5000 in OVF mode!
E.g. the D5000 has a very handy LCD, and if the live view would use phase-detection AF like an A550 or A350, it would be a very versatile camera, much more than it is now.
