Feature packed, pretty much everything worked out of the box. Unfortunately for 2X I am not using their server-side solution so I dont know anything about that side.
It seems that turning off sound in local resources confuses the host into thinking it should disable sound altogether rather than leaving it on the server; that was the only thing I could think of that I didnt like compared to other RDP clients. Obviously a minor point, though, relative to all the things it does right - two button mouse, full keyboard, correct screen resolution.
