I work in IT for a very large hospital system in the Midwest and I run the betas because I know come fall there's going to be some changes I'll want to be very familiar with. Not to mention I help out our own internal app teams to help out with MyChart issues or Citrix things, Vocera issues.. Imagine your nurse not understanding something different on her work issued iPhone while she's in the room with you.. Well, I'm taking screenshots and documenting changes so nurses already know about those differences.
Plus, understanding the low risk (Archived Backup so you can restore Later if Needed = Peace of mind), I don't mind restoring my phone if needed. Doesn't take long anymore. Betas are fun! Unless they're not.. Betas! Yeah! lol
