I'll echo ScotCyGuy's comment. I tried Synergy 2 in the beta and with 2.0.1, 2.0.2, and 2.0.4 but always had to go back to Synergy 1 for any real stability. With 2.0.8 things are definitely better.
I know there are still issues (and always will be) but just wanted to say that it is definitely working better.
