I like that it is easy to use for both patient & practitioner - no need or desire too learn how this works before actually using in clinic/practice! It can be very complex at times but if you take your time getting used all features then its not so hard once set up correctly (I've only been working with version 1 however we are moving towards 2 soon).
The software has made some things easier than previously done especially when looking specifically around cardiovascular issues e-charts etc which have helped me make decisions about treatment options much more clearly now compared other tools out there such as Heartview.
