Personally I have HUGE hopes for the *maybe* up and coming linux client
You just do not know how quickly I would ditch windows for a solid linux client and linux server. The only current fly in that ointment is most of the Current Tools are windows only. Trev and Akka...?... I think are working on a browser based tool that I am drooling over. All in all, I see the possibility for good times ahead. I have been tinkering with a personal server, trying to teach myself, for a while now and it is a lot of fun. This community, including Kayen and Trevius, is a great place to spend time!
Have a good one!
