I agree with most of your points, except these:
1. Does Android have folders? If I remember correctly it doesnt. I remember using a folders app, but it sucked bad. Aside from folders, iOS handles app management better on the home screen. On Android, if the screen is full, you have to move an app before you can put anything there. On iOS, its smart enough to do all of this in one step.
2. Without GPU acceleration (iOS/WP7 uses this), Android will never be as fast or responsive. Android phones would need a dual core SOC to match the same performance you can get from a GPU.
3. Isn't the Apple App store close to 300,000 apps now? That's besides the point, what I'm getting at is that Android apps aren't even close to rivaling the quality of iOS apps. Android fans like to bring up fart apps, but the fact is that Android apps is a fastfood burger, while iOS apps is a filet mignon.
4. True. Aside from music though, iTunes is a one stop shop for syncing. Photos, notes, books, contacts, apps, calendar. If you have iPhoto, syncing/management of photos is phenomenal. Geotagging, face tagging, albums, events, all of this syncs to your iPhone.
