For all you Apple haters responding here; (a) you need to get your facts straight...
You want facts? Okay, here goes:
The Mac GUI was lifted from the Xerox Parc (so much for it being "original").
No other company tries to control what you can and cannot do with your software and hardware (so much for it being "open source"). This is one of the major reasons why Windows runs on the majority of business computers. The other being, of course, that Microsoft doesn't care which hardware you run it on.
Cannibalising the market for the 1DsIII with the introduction of the 5DII --- actually, NO; this doesn't cannibalize that market at all; these are for different markets (I don't think you understand build quality, waterproofing, etc.)
Yes, it does. What you fail to realize is that many professional shooters will forgo the build quality, waterproofing, etc. and choose the 5DII because the sensor is essentially the same at less than half the cost. Sport and wildlife shooters are usually the ones who need the waterproofing, and they use the 1D line (1.3x crop), not the 1Ds.
Oh, and "leading" and being "first" are 2 different things.
