Just received notification and went to order. Shipping to my location (Nordic region) turned out to be expensive enough that I’ll have to pass on this for now and live with older hardware for a while yet. Too bad!
And you'll need the keyboard if you want BIOS passwords or full disk encryption. No OSK or bluetooth keyboard will be available until you're past those.
Biggest downside is a 3-4 month lead time though, I'm too impatient for that unfortunately, especially given this would be a bit of a punt for me.
