I short-listed some Windows Twitter clients as below:
Video URL: Seesmic Video (soon)
Video URL: 12seconds.tv
Although, I find that supporting editing Facebook status feature is interesting, I still pick DestroyTwitter. As this client supports tr.im for shorten URL and TweetPhoto for picture loading in Twitter.
As both bit.ly and tr.im are having more then just shorten URL. They also provide real-time tracking on the clicking links. Beside have iPhone application, Mobypicture also supports the ATOM-publishing protocol for Nokia S60. We also know that TwitPic is the most popular for twitter picture uploading. TweetPhoto have what TwitPic have plus pictures are automatically geo-tagged and an integrated URL shortening service.
