I tried Sync yesterday, but didn't have a lot of time to fiddle with it. What makes it so great everyone's excited? I checked it out and couldn't immediately see it having a clear edge over Jerboa and Connect (but it looked nice)

I was further thrown off by the fact that if I wanted to buy it, I'd need to pay for a yearly subscription (and in that case it didn't look cheap)

Honest question for who can answer
