Tesla Models S is often compered to Ford Model T,
but there is a difference: "Model S" has options to choose from
(not "can have any color you want as long as it is black" with Model T :)
Most of the test drives are done with "Performance" Model S,
that is double size of battery pack (85 KWh vs 40 KWh)
almost double engine power (416 hp vs 235)
and almost double the price ($87,400 vs $52,400, both after $7,500 Federal
Tax Credit)
But they are all nice cars...
Most of those "edu videos" sites have already received some investment...
While video is currently preferred delivery medium,
that is in my opinion a less than optimal choice.
For most classes "enhanced screen-cast" would be better, I think.
Actual screens and content delivered by HTML5 (or Mobile/Flash/Silverlight) apps
rather than or in addition to "plain" videos.
Screens could be "bound" to related content: slides, code, annotations, notes, comments, ratings, etc.
For example, many edu videos for developers are already screencasts,
but not linked to code samples or related data, web pages, other videos, etc...
Ted.com has so far the best example of what can be done, and InfoQ is nice too.
On Ted there is a synchronized text, including transaltion in many languages,
and click on text leads to matching section of video.
A year ago I have experimented little bit with AI-class and Udacity Robotics,
but as YouTube API changes, that stops working..
