Another example of a heavily web-based service I might have used but never tied myself to because of the likelihood of it disappearing. Creates a bit of a self-fulfilling prophecy, I guess.

At least in this case the native app continues to work... would be even nicer if it were reissued as a free app so users didn't have to be so paranoid about not losing their local backup copy, but I guess I can understand wanting to avoid whatever the legal complications of that might be (plus the $99/yr app dev fee).
