I don't really like e-scripts for long term medication as it can be quite hard to know when you last filled it, how many repeats remain, etc. That might just be the app that my pharmac_ uses, but I have tried 2 different apps (one from Priceline and one from LIFE) and they were both harder to use than paper scripts.
Where the e-scripts are great though is for one off medications, and if you travel domestically and find you forgot to pack one of your medications, you can just go and get another one (don't bother asking me how I know this

!)
