Mmh, will have to think about it. It's attractive, sure, and sounds like it
would protect me from more failures, but smells of requiring a lot of
maintenance on upgrades. I don't shy away from sysadmin jobs when necessary
but, given that I already have the horrible geek disease of recording 10x
more things I'll ever have time to watch (which is where all these wasted
terabytes go), I need to keep in check the other geek tendency of spending
more time fiddling with the system than actually watching movies on it, if
you know what I mean ;-)
