Dual Systems and Cameras as Computers

James Duncan Davidson writes:

Not having a single answer isn’t all that surprising. In fact, having an easy answer for a period of time when it comes to digital SLRs may have been a fluke of history. ... The design decisions made by the camera makers are producing really good results in some areas with compromises in others. This means that sometimes Canon is going to be the right tool, other times Nikon.

The problem I have is that my own photography takes me into situations where I want the best of both worlds. I’d really like Canon to provide solutions that cover the full range of what I do, and many of my posts of late have reflected that point of view. I could wait another year or two, or even three for Canon to produce the camera I’d like them to make, but I have more immediate needs.

Could we all just agree on this? Think of the time and effort we would save by dropping the endless and unresolvable Canon vs. Nikon debate.

I'll be interested to see how Duncan gets on. More than any megapixel count or other technical factor, it will be interesting to see how a dual-system shooter copes with avoiding mode errors: Canon's button is here, but Nikon puts a totally different button in the same place. How easy is it to flip the brain into Canon Mode or Nikon Mode?

For my photography, the Canon EOS 30D has been an absolutely stellar performer. I've lost the precise count, but I think it now has around 70,000 shutter actuations on the clock. It has almost never let me down. I don't have a pressing need to go to another manufacturer.

Sure, I would love to pick up Duncan's used 1D MkII, but I keep coming back to my Cameras-as-Computers question: "is it better to update your prosumer model every time it’s upgraded, or to buy a high end model and keep it for years?". I'm almost at the point where I can justify upgrading my 30D to the newly-released 50D, but I'm in no hurry. In any case, the release of the iPhone SDK this year destroyed any spare time I had over the summer to do photography.
