Yes you lock up the mirror for sensor cleaning (when you don't want to use the auto sensor cleaning feature), but when you put the camera on timer mode and press the shutter, the mirror immediately locks up and gives you either a 2 second or 10 second delay before recording the image.
Why do you take photos? To capture the moment, or to document something, right? All of these cameras can do this, and the images are almost all of equal quality. OK, so image quality is around equal, and therefore, a non-issue. Assuming you're a casual user and just want some casual,arty, or photojournalist style shots, the MOST important thing is how the cameras feel ergonomically.
If your photographic needs are greater than the above, the lenses, autofocus (AF) system, and flash system ARE a real issue. What do you want to shoot?
Sports? It's between Nikon and Canon. You can add Sony as the 3rd option. In the past, Canon had the benefit of better high ISO noise control, which allows professional sports shooters to use a higher ISO and a faster shutter speed. Very important for pro sports, but not to me. Currently, it's either a tie, or Nikon has the lead. I don't think anyone can say Nikon is behind right now.
I have also seen some excellent Sony shots. Sony have the lenses to do the job as well, and the A700 has the AF speed to keep up with Canon and Nikon.
Portraiture? I'd say Nikon. Better flash system than the rest.
You want image stabilization in every lens because you have shaky hands. Pentax K10D and Sony A700. The A700 is suppose to be a fantastic, fantastic camera that's equal to the 40D and D300 in image quality.
You want ruggedness....the toughest camera out there. Probably the Olympus E-3. Their lenses are also the most prepared for bad weather. Heavy rain, buildings tumbling around you, I'd probably put my trust in an E-3.
Ergonomics? In my opinion, Nikon feels right. Sony is also very nice and feels natural. The Pentax body is supposed to be good, but from my limited experience (around 5 minutes in Japan), the K10D took me a few seconds to figure out. Maybe it's because I'm used to Nikon.
I found it much harder to get used to the Canon 40D. Sorry, I just can't use it. Same with the 5D that I've held (only twice). I thought the Canon 400D/Rebel XTi was hard to get used to....until I had to use the 40D.
When you're shooting on a beach, on a boat, or even on warm, damp, humid days.
In your opinion. The reality is, it's much more complex.
What if I don't do flash photography? Is it still important?
Is that why 90% of the cameras in the pits at professional sports are Canons?
Yes, it's a good thing that Canon invented the ultrasonic motor. Where would all the other companies be without it? Also, does Sony/Minolta/Konica have any lenses with in-lens stabilization yet?
If I'm doing portraiture, then I'm using a set of Alien Bees or something. Heck, any flash system will work so long as they are consistent on their output. Flash portraiture is more about understanding lighting angles, hardness/softness, and output. It takes years of practice to become expert at it.
I'll take 4 stops in-lens over 2 stops in-camera anyday. Nikon and Canon have it right, IMO.
Why don't you include the the 1DmkIII? It's weather sealed, too. Besides, who wants that yucky 4:3 aspect ratio of the Olympus.
That's funny, I picked up a couple of Nikons and they felt kind of weird, too.
So, I guess we're back to where we started. OP needs to decide on which system suits him best, and simply avoid paying attention to all the over generalizations espoused on this thread.
Gosh, I wish I known that when I was shooting in Celestun last August. From your post, I'm really lucky my 30D survived Hurricane Dean.

ONLY because I'm a Nikon fan... go for the D300.
(Canon makes good cameras too, I hear)
Edit: In response to JFreak's comment, I have a question to the more experienced out there that might help the OP as well... Do either Canon or Nikon really have that much of an edge on the other as far as high quality lenses go?![]()

I have also seen some excellent Sony shots. Sony have the lenses to do the job as well, and the A700 has the AF speed to keep up with Canon and Nikon. I wouldn't get a Pentax or Olympus for this type of job.

Though I may also get flamed about this, I would have to agree with Abstract in part, and say that when you're comparing images from cameras in the same category, you're not likely to see that much of a change in the image quality....
....So to answer your question, you are likely to get equally bad results from either the 40D or the D80 at the beginning of your photographic career. As your skills improve, you will be able to tell whether your gear is limiting you, and will have a better understanding of what you need to improve your pictures in terms of gear.
"People talk about image quality and noisy, high ISO shots all the time, but the slight differences in the cameras is more than tolerable. Again, it's so minimal that it may not be worth talking about. Things like good AF are more important."
AF is definitely important, but being able to shoot 5 frames per second at high ISO also means the difference between getting a shot, and not getting anything at all.
And this isn't just about shooting sports, it's obvious, taking more shots means a higher chance of getting a good one.
High ISO, low noise images mean that you're able to shoot at night, or without flash.
A large buffer means you can keep shooting without waiting for the camera to catch up, and missing your shot.
CMOS sensors allow the camera to process images quickly and easily.
Mirror lockup allows you to do things like attach your camera to a telescope and eliminate the problem of vibration. (so called black card trick).
I honestly don't see how this could be irrelevant unless your shoot only landscapes and only in bright sunlight. Or portraits in a very controlled studio environment.
If you're on the move, the better more advanced camera will let you walk away with a good shot.
A great lens with an inferior camera is also a total waste of time and money.
I think 3 fps (which even smaller models offer these days) are plenty for 95 % of us. Ditto for MLU (which I've never used). These are just relevant criteria if you have something very special in mind. I also think the OP should rather invest in some lenses and a flash already rather than spending everything on his body.
All of the points you mention aren't really relevant for a beginner. The D80 has a large viewfinder (much larger than the current Rebel) and I'd even suggest that he tries the 18-135 kit lens before investing anything. I think a D80 + 18-135 kit lens + SB-400 flash is a very good starter kit. A 40D is overkill.

I think OreoCookie is right that a D80 + 18-135 mm (+ SB-400 flash) is a good setup for a beginner, or possibly a D80 + 18-200 mm VR lens. Amazingly, it's still within the OP's budget! There would still be money left over for something like a Sigma 30 mm f/1.4, or Nikon 50 mm f/1.4 or f/1.8.OreoCookie said:The D80 has a large viewfinder (much larger than the current Rebel) and I'd even suggest that he tries the 18-135 kit lens before investing anything.
