I just looked at the Jolla devices as well and they are also out of stock. I imagine it's probably harder to coordinate selling these devices in small batches; I wish there was at least some kind of availability list I could sign up for.

Yeah, it is a pity all the phones are sold out. It can be ported to other devices though, you might get some useful info here: https://wiki.ubuntu.com/Touch/Devices

4 ubuntu phones and 2 tablets :D
