I upgraded my first generation 30GB Zune from the 1.4 firmware to the 2.2 upgrade. The desktop software upgrade took quite a while. The actual Zune firmware upgrade was relatively fast. It was a busy night that included the previously mentioned iPod touch firmware upgrade, more PC RAM failure (ordered replacement RAM), and debating and then finally participating in the OLPC (One Laptop Per Child) G1G1 (Give One Get One) program (more on this tomorrow evening).
If you want to gory details of the Zune 2.2 firmware upgrade and the new Zune devices, head over to my friend Jason Dunn’s ZuneThoughts website. He has lots and lots of information and video demonstations.
