i think so too. If i hadn't watched the keynote this year i wouldn't have known about ios 11 coming so i would've just waited until i get the notif. I'm sure once Apple pushes out the notifs to customers the adoption rate for ios 11 will be higher. Also, i have the iphone 6+ and ios 11 is very fluid on my phone and everything seems faster too. It's def a great update.The notification most likely did not pop up.
