> 1: The UI: I'll give you that one
Android, iOS, and WP7 all suffer this problem. I think Justin thinks iOS is "better" in this regard because it does a few very common things a little more slickly, but it makes other things harder. I think Justin thinks WP7 is "better" in this regard because he's used to the way Microsoft developers design interfaces, and more tolerant of it. All three of them have utterly atrocious interfaces.
> 2: Resource management: Android Assistant
All three of the above mentioned OSes have their own special problems in these areas, too. 'Nuff said.
> 3: Application sandboxing: Ok
I agree that more needs to be done in this regard. I don't know the state of sandboxing on iOS or WP7 sufficiently well to be able to comment authoritatively on them where this issue is concerned.
> 6: Content partnerships: Not required. User has own services. hulu, netflix, pandora etc 7: The patent mess: What does this have to do with Android functionality?
> 8: Form factors: needed something to round out the "top 10"?
Some of the physical form factors for Android devices are better than anything available for WP7, and the iOS form factor is awful -- it just happens to be above average for smartphones overall, and is consistently so because there aren't really any options from which to choose. The best device form factor I've seen was the HTC Desire Z, also marketed with some altered hardware specs as the T-Mobile G2.
> 9: Support: lots free online forums for anyone who can read
As for official support, that depends on the service carrier and device manufacturer. To varying extents, the same applies to WP7 and (to a substantially lesser degree, because there's only one manufacturer and it maintains autocratic control over service carrier options) iOS.
> 10: Security: haven't heard of a single issue. again AVN Antivirus
I have yet to see a major-league smartphone OS that isn't a security nightmare. The only smartphone OSes that are, by default, anything close to reasonably secure are fringe players (see the Debian derivatives on devices like the Nokia N9000, for example) that don't tend to gain any traction in the market.
