PodTech’s videos work great on the iPhone. You just need to download the iPod versions of the videos. Here’s a few vids you should watch:
A very interesting conversation with the founder/Chief Scientist of VMWare (he teaches computer science at Stanford University). iPhone/iPod version.
Anyway, there’s a ton of other great video over on PodTech.net with a variety of different shows from environmental shows, to lots of shows about new technology.
Every day I put a new video up on ScobleShow, too. For those of you who are new here, I interview geeks and tech executives. Since starting my show I’ve interviewed more than 200 interesting people about where the tech industry is headed. You can put download and watch all those on your iPhone.
