I like that it is easy enought even when you are new at this type of thing! It makes collaboration with other people so much easier than using email or text messaging alone would be (at least in my experience).
The only downside i can see right now as far if its ease/reliability goes through Google drive but there isn't anything wrong specifically about sync com itself just how well google drives integrates into everything else these days - which means we don’s have many options anymore unless someone wants us all working from home 😉.
