I am collecting all sorts of useful resources from the Windows Mobile developer seminars I've been co-presenting at in Alpharetta and Charlotte. I'm providing them for you through our new MSDN social bookmarking site - http://msdnbookmarks.com/ . The direct link to my bookmarks in the mobility category is http://social.msdn.microsoft.com/bookmarks/en-US/user/Glen%20Gordon#sort=recent&page=0&tags=mobility.
That whole site is useful as well, feel free to explore my other bookmarks in other tags at http://social.msdn.microsoft.com/bookmarks/en-US/user/Glen%20Gordon, or the main page for bookmarks provided by many others in the social space.
That list will grow over the next few weeks as I discover more links, so check back often. I won't be blogging when I find new links, just adding them to my list on the bookmarking site, but the view will show you new links at the top, so it should be easy to find them.
