yep, good points, agree all 'round.

One thing in the analog world that may be appropriate is that we do not 
view all collections as equal. In kicking this around locally we've been 
discussing different levels (or insurance policies) per collection 
depending on things like how unique it is, born-digital, cost to re-scan 
etc.

I still tend to think that the TCO of this is generally underestimated 
in part to due to consumer prices for storage.
