Synergy 1 is much better but not without glaring problems (reconnect issues, keyboard disable till reboot on server, etc) but synergy 2 is one of the worst pieces of software I've experienced in a while.
Take everything good about synergy 1, break it, cut down features, and hold your hand out expecting cash.
Utter garbage.
Have you used the software? None of us get paid to do your QA for you.
Once you start handing me cash, I will, sure. But there are many evident issues if you use synergy 2 for more than 10 minutes.
