It's also possible to play an entire round of golf with only a putter. You just have to accept that it may not be the best possible experience.
Battery life is better, and there seem to be less crashes and bugs, but IMO, it's still not a DD candidate - at least in my case. There are stiill a lot of issues to be fixed and many apps won't launch or run properly with iOS 9 beta 2.
Go for it if that's your bend, but I'm still running it only on a test device. YMMV.
Which apps are you having issues with mostly?
