I don't think you're making any good points here.
1. iOS updates made old devices slower under Jobs.
2. people didn't like iTunes 10 and earlier either
3. no argument
4. iPhone has replaced the iPod for most. This was Steve's vision, too. See the original iPhone announcement.
5. Steve had a track record of contradicting his one previous proclamations. He never let his previous statements get in the way of a good idea. And it's hard to argue the mini was a bad idea. Also, there's a good chance they arrived at 9.7" based on things like feasible display and battery technology of the time. Also, he made that statement at a time when 9.7" was at the limits of feasible display technology. As the tech changes, so too would the best size. Even according to Steve.
6. Well, OK, I guess you can attribute that to a lack of Steve, but it seems purely speculative. It's also a really small thing.
7. A7. Mac Pro. Mainstreamed fingerprint authentication. iOS 7.
Well that is one way to look at it.
1. The only iOS that was really slow under Steve was iOS 4 on iPhone 3G. After that Apple learned the hard way to cut off support if the performance suffers. For example, iOS 5.1 (under Forstall) ran smooth on iPhone 3gs, 4, 4s, ipod touch 3g/4g, iPad 1,2,3.
Now with iOS 7 it runs slow/applications crash and not as smooth as iOS 6 in the following devices: iPhone 4, 4s, ipod touch 5g, iPad 2,3 and Mini. iPhone 5 and iPad 4 is not too bad.
2. iTunes 11 like iOS 7 is quite a change and some hate it.
For example:

Many seem to hate that coverflow was removed. Steve Jobs introduced coverflow in one of the keynotes and I believe he would have never removed this feature.
4. If that was true, Jobs would have never released an iPod touch. At the iOS 4 keynote in April 2010, Jobs said 50 million iPhones have been sold while 35 million iPod touches were sold.

Now the iPod touch is pretty much dead under Cook.
5. Possible Steve would come around with a smaller iPad but I doubt it. For example while Steve was alive, the iPhone was the same 3.5 inch screen from 2007-2011.
7. A7 was an obvious logical upgrade from A6. If you mean the 64-bit CPU part, I agree it is nice. But with only 1 GB RAM on A7 devices there are less RAM to work with compared to 32-bit 1 GB RAM iOS devices. New Mac Pro looks like a garbage can. When I saw that keynote live using the Apple stream that was the first thought that came to mind.
Fingerprint scanner not sure how much I trust Apple with the recent NSA privacy scandals. Would Apple bend to government demands? I believe under Cook they will. iOS 7 is a very divisive release.
