You many not care about function changes in FROYO, or even that it has Flash....
What I want is the performance gain. Engadget shows a stock Milestone get 6+ MFLOPS on 2.1, it is geting 40+ MFLOPS on 2.2.
That's an incredible increase ..... like getting a brand new phone for free...
This means Droids and Milestones purchased as much as a year ago could still out perform the iPhone 4, and there will be a generational split in the games on the market as post and pre 2.2 gaming abiltiy.
