No - please give reason. I don't need it. I like it, just have no use for it. Plus it only runs in Windows.
Yes, I use both it and TrueCrypt. I put sensitive information in a TC container. But AC comes in handy as simple password protection for things that while they may not be overly sensitive, you wouldn't want your mom/kids seeing. Or for anything personal... for example I keep a "dream journal", and there's some weird stuff in there.
