A short time ago, the new 'Seesmic for Windows' Twitter client (which we previewed here) went through a significant update and the program also came out of 'closed preview' and is now downloadable (in an enhanced Preview Version) from the Seesmic Website.
What makes it different?
So far, a variety of features mentioned earlier but most notably ... seemless (and excellent) integration with Windows 7 plus support for Twitter lists (as well as multiple accounts).
You can read about this latest version here or download it and check it out here.
Note: This past week Seesmic also introduced products for Android and Blackberry based cellphones as well as enabling Twitter's 'location awareness' in the Seesmic web-based product.
