I had Flash on my Droid Incredible running 2.2 (and it wasn't the watered down Lite version either). It was next to useless. Some videos would play, but in nearly all cases, there was an alternative way to view them outside of Flash. And Chas is correct, open a Flash video and you could literally watch the battery drain in real time, in addition to having the phone heat up in your palm.
I just don't think this is as much of an issue today as it was at one time. But if you really must have Flash support, there are ways to do it like I mentioned previously.
Aside from that, good luck with the multitude of Android devices in addition to the BlackBerry Playbook that runs it. My last Android experience was quite similar to using Linux- it looks pretty out of the box, but once you start customizing it, things go south very quickly. I'd rather spend my time USING the device than troubleshooting it.
