I put the beta on last night. Enjoying it so far. I'm impressed with how well it works as far as betas go. I remember ios 9's first beta last year was not near as friendly.
I have an iPhone 6 and have to agree with you RTA, the push to unlock is kind of a pain. I'm hoping it will be less of one as optimizations start coming out with the next betas. Without raise to wake it's a lot less fluid. I like that they tried something new, but not sure how I feel about this one yet. I can't imagine what the push to unlock feature is like without some sort of Touch ID. Assuming you use a pass code.
How's battery life been for yall so far? I burned through a bunch on the way in today using the new maps so I haven't really gotten a good feel for normal usage yet.
How's WatchOS 3 been? It looks pretty sweet.
