I don't even have 2.1 on my phone! (I haven't loaded the leak yet - but I'm getting so close to doing it!) And you're telling me 2.2 is maybe soon to be out?? auto updating - I am nodding my head at your points. Have you posted a list of your favorite apps recently? I know you had another version.
2.2 is still in it's early stages, but we won't see it in our devices until next year. And the writer (not I) of the article brings up some good points about auto updating. I have 1.6 on my MyTouch, and favorite apps have not changed or grown lately. I have been using my new HD2 for the past few weeks.
