While I agree in principle with what you're saying, this specific 
comparison would be better stated as "What is the cost of data 
corruption multiplied by the risk of that corruption occurring?"

The cost of upgrading is known and unavoidable.  The cost of data 
corruption, while probably higher (unless Achilles has an effective 
backup/restore system), needs to be factored by its probability of 
occurance.

Of course, neither you nor I are in Achilles' shoes, so trying to figure 
out where they pinch is academic at best.
