Honestly, I'd say no because by the time camera technology catches up with the card (assuming it's one of the newer 600x or 1000x models), it'll probably be dead or not worth much. Well, ok, technology evolves at breakneck speeds, but you get what I mean. First thing I'd make sure before deciding is whether it impedes or gets hooked up on any of the card reader or camera internals -- if it even comes close, that's a good reason.
But either way, given the high markup and premium status of the card, I'd say that giving Lexar a call wouldn't hurt, at all. Companies tend to be a little more helpful to people who buy their expensive tiers.
