Here is my take, which I suspect is a good example of many riders like myself. As I said in this thread a while back, I would be very curious to try out discs on a bicycle, as I had motorcycles for years and cirucuit raced a bit, I can completely appreciate the modulation and all the other good stuff.

In general, Im happy with cantis and Vs, especially with good pads and keeping rims clean--but can completely see how grungy conditions etc are where its at with discs.

Its good to see comments from mtn bikers who have crashed their brains out for years using discs give comments on how a rotor doesnt go "patooey" with any fall, and Im sure much of my hesitation for discs is simply because I dont have experience with them, and so also dont have the experience mucking around with them mechanically. For this reason, a bike with Vs or cantis is a completely known situation, and you know that throwing your bike into the trunk of a car or on top of a bus will not ding them, and tools wise its pretty much a no brainer to change pads etc or adjust them. (again though, its probably not much to learn this stuff with discs).

I can completely see going mechanical so one doesnt have to worry about bleeding issues (as mentioned, hanging a bike from a hook can cause bubbles--some other persons comment, not mine)

When the point about a slightly warped disc rubbing pads comes up, this does pique my interest. Ive read cycco saying that 1mm is all the play one has--and then others say they've slightly bent a rotor and straightened it by hand and it was fine....so as someone with no bicycle disc experience, how does one take these diff takes on it?
I personally hate having pads rubbing on a rim on a bike, it bugs the heck out of me, but then Im pretty careful with keeping my bikes in good shape in general--but then I wonder is cycco overexaggerating? Cycco, I suspect that you are a real picky fellow for things so its hard to know how to take your point of view over the mtn bike guys who say they toss their bikes off trails regularly and dont have issues. It really is hard to know for someone without experience. I guess I will just have to own a disc equipped bike to see how pad rub is in real life and if it bugs me or not.
I suspect too that diff mech disc models play a part here, diff build quality etc (as with anything) and so perhaps diff models are much better for keeping tolerances and/or tweaking of things.
