The gpu and dsp have proven at least in Nokia demos that Flash works well. The version of Flash on the Hero is not as robust as the 9.4 version on the N900. Adobe has stated that mobile device need a dsp for a complete Flash experience. The 7201 chipsets of G1, etc will be let down a little with expectations of 10.1 Flash.

Droid is Flash ready, which means the hardware and OS version will work with it when released in Spring.
