Jim from Sparkfun team is lucky enough to have an Intel Galileo development board in his hands and he shares with us his first experience. Through a small project (Unread email counter) he shows us what to expect from Galileo. Joining Arduino sheilds and libraries with the power of linux looks like a nice combination. Of course we already have Arduino Yun but Galileo has better features (like faster cpu, more memory etc).
At last I would like to mention that Galileo is an open source platform and if you are interesting in how it works you can download the Galileo Schematic. Intel also has a nice Galileo_GettingStarted in which you can find lots of information.
Link for Jim’s review is this one.
