I just wish sites would use HTML5 video tags properly. Most are still just detecting the user agent strings and feeding HTML 5 video to iPads and IPhones only. This is the wrong approach. Instead they should detect the platforms capabilities and use what is best in the situation.
6 months later, and this still seems to be the case. Maybe with the recent announcement from Adobe that their streaming server 4.5 will also serve HTML 5 video for iOS/Roku clients will help fix this properly.
Having now had hands on experience for a while with a tablet with Flash (The HP Touchpad), I'm firmly in the "don't want" category. The video experience is painful and noticeably bad in most cases on the Touchpad. iPad, continues to deliver me solid video playback on the sites that support it. And the ones that do continue to grow.
