The ability to move files between programs seamlessly, being able to view documents online via Google Drive or Dropbox is great. I haven't found anything that really bothers me so far but there have been times where I've had problems syncing my computer screen with the website due to issues with browser compatibility. If you're looking into moving data from one program/system to another this could be an option! It works well for us since our accounting software does not sync well with google drive and we needed something quick and easy.
