Chris, I hope your son is doing better. This snow thing is getting old. And it certainly hasn't warmed up much but Sunday looks like could be spring like on the coast.
I have Version: v1.9-48-gdef33af working on the Pi Zero W I got a couple of days ago. The build process worked as expected should. The UI doesn't have the fancy Zero icon at the top right but apart from that, all the standard stuff seems to be work pretty well.
That is, except for the onboard wifi. I thought it was the same as the PI 3's internal wifi but I can't see it in the UI, and have not been able to enable it using the command line. Any chance you could give me a few pointers on what I should try.
