Yeah, for the professional, Critical Updates & system backups are like manna from heaven - it's boring and frustrating as hell, but it's absolutely necessary and can be very, very lucrative.
However, for the amateur, that stuff can drive them bonkers [and they don't get paid to do it].
PS: What're they charging for Ghost Enterprise these days? [Off the top of my head, I'd guess at least about $100 per client seat.]
We paid $6,700 or so for 350 licenses. I think that's around $20 per license on a volume purchase.
