Well, it's still a good question - for me
FWIW I have it on my computer (I think because I got it on offer for 10 dollars or so). I use it occasionally, but have yet to do a test restore.
I'm low tech, so I use O&O & Windows7 image-backup and if anything goes really wrong, I'll pray that one of them will work. If not, reinstall.
It has an apalling interface, but not much worse than Acronis before it (my previous imaging software). Otherwise it all comes down to that restore, hopefully far in the future...
