Sorry man, I didn't mean to be a jerk. I just got a little incensed at the implication that the people buying this camera don't know what they need or want nor how to get choose the appropriate tool for the job.
Interestingly, of all of the items that you list below, only the
frame rate has any approximation of truth to it. And if you are
good at it, even that is questionable. I work with a dance
photographer, with 20 years experience, and she can photograph a
dancer at the peak of action, at single frame settings, and get it
right almost every frame. I'm getting there myself. We know dance
well enough to predict the action... do you know Karate well enough
to do the same? Concerning having camera that has enough response
Actually, I shoot Aikido, not karate, and the fact that it's a throwing art and not a striking art means that there's lots of people flying through the air. Catching the moment where the angle of the person being thrown in relation to the thrower is just right is VERY difficult, especially with a D60. And besides that, I want (need?) to take a sequence of shots and composite them together to show the complete sequence of the throw from beginning to end. I suppose I can use a digital video camera for that and just capture the frames, but then I'm limited to only 1.7megapixel or so.
to catch a kid smiling, any DSLR is responsive enough to catch a
kid smiling... if you can't do that, you really should check your
reflexes with a doctor. And as far as buying the camera "so I can
Do you have kids? If you do, then you realize that when they're young, they're expressions and moods change quite rapidly. Also, the fact that they're flailing their arms around uncontrollably means that getting the frame where the smile was fully formed without the arms in the way is literally a matter of fractions of a second. In addition, shooting a series of images where you can see the whole sequence of a particular emotional reaction from beginning to end is just plain fun. To see be able to see, frame by frame, the complete development of a facial expression, to see in sucession how first the lips curled up and then the cheeks puffed out and then the eyebrows lifted and then the eyes opened wide and then the mouth opened and then the tongue moved forward.... you just can't catch that with a D60. You would have missed a lot in between.
take it to the beach"... well... let's just say that you would
never catch me using a $4500 camera + $$$ lens at the beach to take
casual photos; in a professional setting, yes, but casually...
I don't take casual photos at the beach with my MKII. I photograph the models that I bodypaint at the beach. Check out this link:

This was done at a reservoir INSTEAD of the beach where I really wanted to shoot it.
never, regardless of camera build. You want trouble... change the
lens on your 'sealed' camera on a sandy beach with even a slight
breeze blowing (not just sand, but salty humid air on your sensor.)
I don't intend to change the lens on the beach.
Another fact that I find interesting is how utterly angry some
people get at the fact that I have the gumption to even ask what is
so great about this new camera that it's a "must have". There have
I didn't get angry at that. I wouldn't have gotten angry at that. What I got angry about was this:
"I guess that if you are a professional sports photographer, someone that makes a living at it, this is really a good tool... but if you are at all outside that category, why do you need the camera?"
You didn't ask "Why do I need the camera?" You asked "Why do YOU need the camera [emphasis mine]?" It didn't sound like you were trying to get answers for yourself.
Also, there's more out there than professional sports photographers who have a use/need/want for a camera like the MKII. I've been wanting to get an EOS-1 digital body for a while now. I was all set to get the 1D just two months ago, but when I heard about the MKII, I figured I would wait for it instead.
There's a whole other aspect to this discussion and that is the aspect of going straight for what you need/want rather than incrementally stepping into it. Doing the latter means that you ultimately spend more money. Let's say because I'm not happy with the autofocus of my D60 that I upgrade to a 10D which is better. So I sell my D60 for $700 and buy a $1500 10D. And that holds me for a while until I decide that I really do want to take shots at 8fps for my aikido stuff. So what I do? I sell my 10D for $800 and buy a MKII. It would have been better if I just bought the MKII and saved the $700 that I lost on the 10D. I've been through that cycle enough times with my studio strobe equipment (going through a Dynalite system with a M500XL pack and 1015 heads, then 2040 heads, and THEN 4080 heads then a M1000DR pack) that I just said "screw it" and went straight for what would get the job done in the least amount of time with the least amount of effort. That happened to be a Profoto D4 system at $5000+, but it was money well spent.
Anyway, sorry for being a jerk. I hope I've given you a better answer this time.
