No, they haven't made it any better in 2.5. It looks pretty much exactly the same. The one really nice thing they did in 2.5 (useful for deploying servers from templates) is the ability to specify all of the network settings (for a static IP like most servers would have) and have it prompt you just for the IP address when you create the VM. That way there's no more "edit this customization before proceeding" nonsense to fix the NIC settings.
Thanks a lot for your response. I'll do it that way until they fix the wizard to allow OU selection (and it seems like it would be such an easy thing for them to do..)
