*Edit: The below was written before Lion came out, so this post is referring to what is now called "Legacy FileVault", which encrypts only your home directory.*

I've enabled FileVault on my computer and haven't had any problems yet, but I've read online that FileVault has issues. What are these issues? Are they out of date and fixed in Snow Leopard or are there still problems that I might have in the future?

I like the idea of my disk being encrypted, and it hasn't seemed slow to me, but I'd like to be aware of any possible pitfalls that currently exist with FileVault.
