If you're an iPhone owner, you probably don't want to hear about Flash. Full support for Adobe's rich media technology has been promised for the iPhone many times, but it's still not there yet.
However, if you plan on getting the Nexus One, you'll be one of the first users to be able try out Flash Player 10.1, currently in beta.
Adobe posted a video showing the latest Flash Player happily working on the Nexus One. It can be used to browse Flash-heavy sites and play online games, but it can also be used to deliver Flash-based ads. From what we can see in the video, Nexus One's powerful Snapdragon CPU handles Flash with ease. Check out the video below.
