jkkmobile posts on YouTube a video of Vista (RC2) running on a TabletKiosk eo i7210.
Drivers are still missing (such as the graphics driver–so Movie Maker doesn’t work), but it looks nice. I was pleasantly surprised to see the floating TIP working, for instance.
I’ve been concerned about Vista’s performance on these devices, but it doesn’t look bad at all. And Media Center looks very nice.
