1) It deletes everything on both drives - backup everything!
2) I installed Mountain Lion to an external drive and managed everything from there.
3) it requires using Terminal. I don't really use Terminal, but I copied and pasted from the instructions and changed commands to suit my setup.

I'd much rather a Fusion Drive which created a copy of the most-used files on the SSD, rather than moving them. Okay, so you'd have 128 GB less space, but there would be redundancy, the HD could be cloned to a same-capacity drive using SuperDuper, and you could even remove and replace the SSD without any loss of data.
I'm not wishing for people to lose their data, but I hope there are enough cases of this to push Apple into giving us a Fusion Drive option like the one I described.

That's a valid point, so the take-home message is: get your backup (Time Machine, or whatever) house in order before you use a Fusion Drive Mac.
Which, really should be no different from what you should be doing anyway. It's just playing Russian Roulette with two rounds in the cylinder.
