I have a Galaxy Nexus, and I know this will be an unpopular opinion, but I find Flash works pretty well on the device. Granted, I only use it for video content on sites like the BBC, but the underlying functionality is fine. I don't think Flash has a future on mobile devices, but HTML5-based solutions aren't up to scratch for general use yet, so I don't think Adobe should throw in the towel just yet.
Yes, Flash can still do stuff that HTML5 can't, but it really doesn't matter.
