Been using edge releases on my Pixelbook i7 for a few months. Much of this is pretty baked. I wish USB support was here so I could use my Yubikey 5c to do SSH, but otherwise it's fine.

From my experience Docker works fine. VS Code works well. You can install your own Terminal if you want.

Note for the demo in the video they ran Chromium inside the VM so localhost would work. Otherwise you need to use the penguin.linux.test domain which was pretty hard to find out about when they made that change. Another thing is you really should default to binding to 0.0.0.0:$PORT because that makes your life easier as well.

For those not enjoying MBPs and their keyboards the Pixelbook's keyboard is pretty good.

If I had to make a recommendation I'd say that getting a lower -end pixelbook would be a great buy. Not sure my i7 or extra SSD space has really been worth it.
