I love that we can access our data from anywhere with an internet connection! It's easy enough so even my 8 year old could use it without any training or assistance at all (I'm not kidding). The interface isn't as intuitive when you're used to other programs like Microsoft Excel - but once again this may be because of age/experience differences rather than anything specific about SL itself. We've been using SLS since day 1 after moving into our current location last fall; there are many benefits including ease-of-use & accessibility via mobile devices which has made scheduling much easier overall.
