You said it yourself, Bub: Apple knows what's best for us.

After the whole "Save As" debacle, I'm not sure that would be such a great thing. The two reasons I dipped my toe into Mountain Lion were that a) You tried it and said it hadn't broken anything ;-) and, b) iApps were supposed to get Save As back -- it's really been a huge problem working with Keynote ...

Alas, no Save As that I can see (at least, it certainly isn't a menu item), and Cmd + Shift + S = "duplicate," unlike pretty much every other app out there (way to "think different" Apple) ...

So anyways, since I could not care less about notifications, integrated social links, documents in the cloud, etc., there doesn't seem to be much compelling me to switch over to the new OS on my other machines. But at least you're right that it hasn't really broken anything so far, so they at least got the "do no harm" part a bit more right than last time ;-)

I actually wonder where Apple wants to end-up with its OS X strategy -- seems more and more they want their Macs to be just iPads on a desk, which is kind of depressing =P

Drop Box

I use DropBox, but what I don't like a/b it is that you have to make sure you copy files or folders (Optn/drag&drop) because once you pull that data off onto another computer, it's gone. I prefer file sharing or bluetooth sharing because you know the original stays put on your drive.

I went the early adopter route after all because after sitting on Tiger so far past its usefulness and watching other software upgrades thumb their noses at me in a steady parade, I decided to roll the dice and make the move now.

Plus for years, my two Macs were out of sync. The MBP that I just replaced was light years ahead of my Quicksilver G4, and then when I replaced the G4 with then Mini last December, it was extreme leapfrog. So now, I have two Macs that are at total parity. Balance is a good thang...

Of course, there's AirDrop now. Will have to see how that compares to file sharing.

Dropbox can be used with Time Machine. I've recovered old deleted files, no problem.
The best Mountain Lion feature for me is getting the same, or better, speed I had with Snow Leopard.
Lion seemed sooo slow.
