If you're a diehard TechEd 2013 fan, or just missed some sessions stuck in the Microsoft Surface line, Tim Nilimaa has put together a slick utility to give you the ability to download all of the sessions (including the session slide decks) from TechEd 2013 North America.
The app requires .NET Framework 4.5 to work, so you'll need to grab that and install it if you don't have it already, but it provides a great way to obtain all or some of the TechEd 2013 sessions for viewing offline, particularly for those new Surface owners.
The tool is being steadily improved and kinks worked out. There's two versions you can download, one with an updater built in, and the other just the standalone download.
You can download the latest versions of the tool from Tim's blog here: Session Downloader
