Here are two samples of video, one shot with the Nokia 6680 and the other with the Treo 650. Both are just shots of a few seconds of traffic out of the window at the office. The Nokia sample was shot with the back camera (the 1.3 megapixel one) using the built in camera application, which also takes videos:

The second is from the Treo, also using the default camera application, same subject, videos taken pretty much back to back:

If you would rather download the video directly:

Definitely very cool that the both of them record in 3gp format, it would be fantastic to have just one format to deal with for mobile produced content. One of the major improvements with the 6680 is that it will record video in arbitrary lengths now. The 6600 capped video at 10 seconds so that it could be sent via MMS, which made the system pretty much useless for video for me. The 6680 comes with a video editor even, I need to fool around with that. It would be fantastic to be able to video blog directly from a handset.
