I'm pretty surprised that the dust issue was not raised by Michael, and only one person here has mentioned it. I have being using my Oly E-1 for about 2 years now, including in some very dusty environments, and I frequently switch lenses. I've never had to clean the sensor. In fact I've never even had to think about. Perhaps two or three times I've manually activated the SSWF to clear a speck, and it worked. The rest of you don't know what you're missing.... (yeah, I know what I'm missing: resolution, low noise, fast focus :-) ).
I'm not so sure about increasing the complexity of cameras. Voice control...hmm, interesting idea, but surely that is a solution to a problem that would be better resolved with better ergonomics ? The whole SLR design paradigm is still stuck in what the French call the "gasworks" paradigm, and piling on yet more "features" is not a good solution. There is room for a total rethink, although this would scare marketing sh*tless - the fate of the Oly E-300 is not comforting. Voice control _might_ be a solution, but certainly not _the_ solution. I can just imagine how well this would go down in a wildlife hide, or in a church. A complete, ground up redesign, taking advantage of the freedom gained from losing the film door and winders, and based on solid usability and ergonomic principles, could result in a very different looking device.
