Larry:

I've been thinking about this since Sonny's message earlier today.

I've had problems with 18+ months old, but unused, Epson 2200 ink 
cartridges being rejected when inserted into my 2200.

So, I'm wondering if the flash memory in them is more volatile than I 
had previously thought.

If so, then perhaps images won't last long enough in SD/CF cards to be 
all that useful for long term back-up.

But what do I know, I went to art school. :-)
