A lot has happened in PDC 2009. Although I couldn’t make it this year, I’ve been watching it very closely from the keynotes, session contents, technologies, attendees, the space, chill out zone and merchandising. XAML-wise, there were some glorious days.

Some cool WPF 3 and 4 apps were shown in day 2 of this year’s PDC, like Saesmic, a Tweeter and Facebook desktop client for MAC and Windows, Pivot, from Microsoft labs, Fishbowl, another facebook desktop client, and I’ve been inspecting every one of them. Aside from the release of Silverlight 4 Beta, IE 9 video demo, Office 2010 Beta, these apps made the delights of the participants as well.

Saesmic

In the day 1 Keynote, featuring Ray Ozzie, Chief Software Architect at Microsoft, Saesmic was announced as a feature-rich native application for Windows now available.

Partnered with Microsoft, engineered for Windows and optimized for Windows 7, this preview version of Seesmic for Windows combines the best features from Saesmic web and provides them in a native Windows environment.

Fully functional with Twitter, Seesmic is a simple yet powerful client application that allows you to:

• Manage and post from multiple twitter accounts
• View aggregated Home, Replies, Private and Sent columns.
• Create and save searches
• View and add to your Twitter lists
• Create unlimited columns
• Enable choice of multiple image and url shortening services
• Manage notification of your messages. 

Pivot

My favorite. It requires an invite for you to install it, but it’s worth it. Pivot makes it easier to interact with massive amounts of data in ways that are powerful, informative, and fun.

A lot has been done in terms of user interaction and data accessibility. The team has made a significant effort in designing an interaction model that accommodates the complexity and scale of information rather than the traditional structure of the Web. Like I said, it requires an invite code, which you can get by submitting your email at the Pivot website.

I would strongly recommend taking some time to read the developer’s information, available at the website. It is interesting to see how data collections are treated and the general architecture of this platform.

Fishbowl

Another sample shown from the uxlabs team at Microsoft is Fishbowl. Fishbowl is a trial application and a sample demonstrating a unique user experience with Facebook content, optimized for Windows 7.  It is available for download by technology enthusiasts and Facebook power users. Since it's currently a trial version, they don't support it. But who cares, right??
