If it's 1% and this is configurable, then there's no problem. I'd
leave the current semantics and live with a small return rate if I
felt data integrity was improved.

True. But if this is configurable then people can decide. The fact
that nobody has patched the current behavior publicly suggests that
not enough people have problems with it.

Actually, I bet they do get 1% return rates or something anyway, so
that's not a big problem :-) I'm already on my second iPod (badly
horribly designed thing - it's possible for the filesystem to get
trashed too easily - but I got it because I wanted to run ipodlinux).
In the case of an iPod, most people care less and Apple certainly
expect you to have copies of all of your *uhum* paid music in iTunes
anyway.
