This just about echoes the reply I got from my old ISP, cowboy.net- I asked
how quickly they used up the linear flash in their router.

They said they'd had the same card for 5 years and were only 5% or so into
it's rated life cycle. I don't know how they kept track.

It is SO nice to have the large capacity storage in one card; I just back
it up a bit more often, and keep all names/notes on internal. If it goes,
I have a handful of small cards still.

I feel a little like Woo: messagepads and cards are multiplying at my
place. But only a LITTLE like Woo has achieved... :)
