John Coyne is a Systems Engineer in the OEM Embedded Devices group at Microsoft - if you attended TechEd 2008 Developers (or stuck around for the second week of TechEd IT-Pro) then you probably saw John either presenting, or on the show floor answering questions about Windows Embedded "stuff".
Anyhow - John has started a blog about Windows Embedded "Stuff"
John doesn't seem to be sure why anyone would read his blog - I think the answer is obvious... John is one of the systems engineers that is constantly in front of customers, so has a real world view of customer issues and cool/interesting projects.
Go take a look at the blog, and add it to your favorite RSS feeds (you can always delete it later!).
