A small but refreshing change in iOS 9 is the font switch to San Francisco, which I've become accustomed to reading on my Apple Watch. Then there's the new app switcher, which is subtly gorgeous.
I'm one of those people who relies on the built-in Notes app to make lists and jot down quick thoughts, so being able to add attachments, photos, and sketches to notes, then turn to-do lists into checklists, is a long-awaited change that I'll be taking advantage of across all my iOS devices. (I'll have more thoughts on the new Notes app later this week, so stay tuned for that.)
My older iPad doesn't have the new iOS 9 functions I want to use most, so using the public beta is making it clear that I need to upgrade to new hardware soon (perhaps to the rumored iPad Pro in the fall). I'm becoming more and more interested in using an iPad as a work machine, and iOS 9 has features that would make it even more useful.
But the beta hasn't crashed my device, or even slowed it down. It's just as functional as it ever was, but now it has some new features that I plan to get accustomed to on my iPhone--as soon as I work up the nerve to install it.
