I had minor problems since using Developer Preview 4 of it, and since I moved to GM, I haven't seen any significant. There is something strange with NVIDIA's CUDA driver (keep asking me to update). There was an issue with MacPorts due to Mono.Framework installed (might've been not related to Lion at all, MacPorts is now at 2.00, so who knows). I'm aquamacs (emacs clone) user, and it works pretty good.
