mmm Interesting thread, considering I've just purchased a 2nd hand D60. To my joy, I discovered CF 15, so I can use the camera and test it without a compactflash card in it!
After playing with it, I'll note a few things:
1. Super quiet shutter (I'm using to the eos1n shutter, which is considerably noisier). Makes me wonder why people are complaining about how noisy the 20D shutter is!
2. Poor autofocus in dim light? From my limited experience, I'd disagree. It focussed quickly, and accurately for me in dim lighting. Of course, I was using the AF assist beam (using a CF so that it emits but doesn't fire). I guess, a lot of it depends on how you define 'dim light'. I suspect many are looking at dim light being pitch black! And dim light is most certainly NOT pitch black. Testing so far, between my eos1n and D60 doesn't show much of a difference in speed/accuracy of autofocusing in general use, both indoors and outdoors. Sure, if you're shooting theatre/band shots, you might have some issues. Basically, after using my D60 for an hour in what I consider dim light, I can't see what the fuss was all about, and why the D60 has been bagged for this!
3. Buffer speed. Tell me now, and this is what really ires me, how many 35mm film SLRs had a motor drive (as default)? Not that many. Sure, the last few years of 35mm film SLR development showed cameras have a 2fps motor drive, and yes, you could hold the shutter button down and zoom thru a film, but let's consider a few things.
a. What's quicker - waiting for the D60 buffer to clear, or changing a film cartridge? I know which is quicker.
b. How often do you really really really need to be just holding the shutter button down and take shots in quick succession? Most photographers don't need this function/feature, so it's a very moot point continually bashing the D60 because the buffer is smaller than the 20D's. Sure, if you absolutely need that buffer speed because you're a sports photographer etc, yes, the 20D is better. But, for most people, the D60 is fine I reckon.
The startup times can be a bit of a nuisance, but I've set my camera to 8 mins for power off. Sure, it might drain the battery faster, that's why you have the Canon dual charger and two or more batteries 
It seems that there's a lot of "there's a newer model out there, we MUST upgrade to keep up with the joneses" attitude out there. The D60 is a fine camera, most of the 'upgrades' for the 10D or 20D are minimal in my eyes. For most users, it'll be fine. Sure, the 10D and 20D are better. There's no argument there from me. I just don't think that bagging the poor old D60 to death is warranted.
As someone else pointed out, everyone raved about the D60 when it came out! Suddenly, because there's a new kid on the block, it's suddenly crap? What gives? Either you really didn't use the D60 when it was current range model, or you're suffering from the must upgrade syndrome.
Depending on what you're shooting, maybe consider selling the D60 to somewhere like keh.com, and upgrading to a 10D (the price differential won't be that much, most certainly less than upgrading to the 20D). I would definitely buy more quality glass for it though
