Is iOS7 functional - and stable and is it ENOUGH for you?

I love Apple gadgets . They are incredible . I live on my Iphone 5S,
I have very few problems with iMessage. I don't get a lot ofr crashes.And whgile using NEXUS 5 when ii'm on my iPhone i don't find myself missing a bunch of minor functionality.
                   Some peoples are experincing crashes with iOS 7. Sometimes iOS interface and windowing systems.
                    That's when screen goes darks , the apple logo appears, and it takes a few longs seconds before you're back on the Home screen . Sometimes it's an app that crashes.
                    Menory , especially on hte 64-bit iPhone 5S , iPad Air , seems to be part of issues.
                    To get a rough understanding of how often it's happening , i asked around. Apple is aadvertising iOS 7 , in part , based on its stability so making it rocks - or deep water - solid simply has to be a priority .Hopefully Apple will kick iOS 7.1 out the door ASAP spo everyone can enjoy its improvement.
