I care simply because there is often a general idea from users here that they need to have the latest without always knowing why they think they need the latest. It's reasonable to ask why someone thinks they need something if there doesn't seem to be a need for it. Maybe I'm missing something (which in this case seems to be true and thank you for pointing out the widget stretching which I didn't see referenced elsewhere), maybe they are worrying about if for nothing. So, your 'bigger question' really wasn't a bigger question after all.
Please don't take anything I say, harsh as I might sound, as directed at you personally - didn't mean it that way - even though I do have a tendency to sound accusatory most of the time. That's not something I'm prepared to work on - just one of the little foibles that makes us who we are
I get somewhat exacerbated when I see posts like that because typically forums are filled with people who want to tell people what they need to get, think, etc ad-nausea. Again, this isn't directed at you - but I've seen post after post that proves it out
As far as "need" goes - there really hasn't been a "need" at all to upgrade versions of Android after 2.2 - from an end-user experience, much past flash - there hasn't been anything quantifiable different from 2.2 to beyond sans some performance improvements here and there - so I take most upgrades as leisurely strolls down the path of security fixes and incremental software releases....so I don't know that I'd say anyone "needed" to upgrade - so to that end, I guess we agree!
