I hate to sounds like a broken record but flash is available on the iPad for $5 video scrubbimg also works fineHardware-wise they're all virtually the same thing. Android does have closer to true multitasking, and is an open platform, but yeah, the iPad's got more programs.
Flash performance isn't the FAULT of Tegra...it's just sites that are designed around having a real PC aren't going to do real great on something vastly less powerful...hence why iOS skips not only Flash, but cheats at rendering in other ways too.
Hmm...I guess HP's Touchpad can mostly handle playing flash video, though I've heard scrubbing through it doesn't work or doesn't work well (at least with the initial software release).
Do wish you could install Flash though on an iPad!
