If Wayland just wanted to be a new and better X server implementation I would like it but from my point of view the planned feature set really looks like Wayland was the system designed first and X second. Especially given the prevalence of virtualization in corporate environments now.
Pulseaudio is basically the management engine that Alsa should have had to start with.
Systemd has turned out to be a lot better than I expected and frankly I won't go back. The documentation and knowledge base seems terribly small though.
