I don't know I'd trust a possibly defective card in my camera. You don't get a second shot at those pictures. I'd probably use it in an mp3 player since the music and vids reside on the computer.
Well I plan on it and if I can't use it on my phone, I have other devices I can use it in. If nothing else I can use i tin my camera and so on, so it will be no loss.

You could run into people creating 64gb SDHC cards, but you just might run into the same kind of problem you saw with 4gb SD cards that weren't HC.
