Worth upgrading to Lion Server?
Not trying to be snarky, geniunly curious.
Currently have a Snow Leopard server for a small business office. It's being used as an Open Directory master, network share, web server, and Time Machine backup. No mail/calendar/wiki (use Kerio for that). In reading about Lion server I'm not sure if any of the new features are worth the upgrade for me. We went from 10.5 to 10.6 server mostly for the speed boosts and Spotlight searching, but I can't seem to find any "must have" Lion features for my use case.
Anyone care to share their decisions over why they are planning an upgrade, and why?
