Let's not confuse progression with trying to go bullet-for-bullet with Android features. They are going to do a lot of stupid stuff that Apple shouldn't copy (as well as doing a lot of clever stuff that Apple should copy, to be sure). I don't understand the preoccupation with having weather on your lock screen, for instance... Most of us aren't farmers. Is it really the most important thing to have up front? Let's hope Apple is thinking about the benefits before they just implement the easiest thing. If you put this on the home screen, that means customers will expect it there and it precludes you from putting something else, more useful there instead. Now I hope they do keep making slow and steady additions to the OS, and maybe there is something better they can do with the lock screen, but don't ask them to rush it if the Android idea is less than perfect. If we had gotten cut and paste right away then we may have been stuck with a lesser implementation (Android) that would have been with us even now. Most normal people aren't so into their gadgets that you can change system behaviors all the time. Apple's end goal, I believe, is to be the stable rock that makes sense. Their marketing stays the same for long periods of time; their OS looks similar for a long period of time; heck, even Jobs' outfit stayed the same for a long time... It's creating a mythos of dependability, and looking over a long period of time they appear more stable – more sure of their footing. Not frantic, changing half-baked features like their competitors.
There are changes I could go for. Ones that really do seem inevitable. I'd love live icons; now that would be a real great improvement. Maybe the weather icon could just show the weather on it. I really don't care that much about the weather. It's sunny out the window and it's June. Safe to say it's warm and it's not far if I want to check it. There's a lot Apple can do to display more information to the user... Maybe they can have a different display of the home screen when you turn your device horizontally. Maybe there's a smarter way for me to control brightness on my iPhone. That's really the only thing I need to return to settings for all the time right now. But I don't know if an icon on the lock screen is the answer. Maybe it is. Maybe it's not.
