I think the better test will really be for when Froyo gets ported to the G1 and seeing how Flash performs then
Have you heard definitively that Froyo will be ported to the G1? I was under the impression that Froyo and even Eclair are too big to fit on the G1. I'd love to be proven wrong -- I have two old G1s sitting in a drawer and would love to put Froyo on them. Froyo arrived on my N1 last night, and I'm very happy with it so far; there are lots of nice incremental improvements. But as far as I know, nobody is working on shrinking Froyo down enough to fit the G1.
Disclaimer: I'm an engineer at Google, but I have no inside knowledge of what the Android folks are doing. I didn't even know Froyo had been released until I saw the giant styrofoam frozen yogurt in front of building 44.
