60% is 2.1, however, and both of these new Android features are only supported in 2.2. I have an Eris that went on sale less than a year ago, and chances are my phone will never be updated to 2.2.
If the phone is 2.1 now, it will probably get 2.2 by the end of the year.
As far as I know this is the first mainstream upgrade of phones from 2.1 to 2.2 (apart from the Nexus which is, imo, niche). Or did I miss any?
