The first comment under the you-tube video was so venomous, it was comical. This video was hastily put together because some people were begging for a video of OS4.0 final update. It's recoded with a camcorder, slightly out of focus, and then compressed like crazy with a lossy codec. Analysing stuff too much would be like telling someone their camera is crap after looking at highly compressed JPEGs.
Where do people get the idea from that it's really slow and unresponsive? The Xnet progress bar? That's progress for downloading RSS feeds via the internet, which is limited by the server's response time. How about loading times? Once processors are above a certain level in processing power, the bottleneck becomes the speed of the drive themselves (usually, even the IDE bus is faster that the drive).
Regarding the star wars intro flashing and not being smooth, it looks a bit like the camera is trying to adjust its focus and exposure settings. However, let me assure you that I can watch (encrypted) DVDs no problem with no frame skipping, and still have processing power left over to do other things.
I think that the final app is a VNC client connecting to a Linux machine of some sort (might even be Ubuntu :-P). Hence the jerky screen updates. At least that's what it looks like to me.
The video may not show it, but I've never seen IBrowse render pages so quickly, or scroll so smoothly as on my A1, and that's running under 68k emulation. The OS definitely is fast and responsive. I don't have those random momentary pauses like I have on my win-xp machine when it's doing goodness knows what in the background.
