It’s not out yet, but there is a kickstarter from German company Volla, coming in the next few days for a 12" tablet running a Mediatek soc that will be capable of running Ubuntu Touch - for which you can use UT native apps, webapps, some Linux desktop apps via their “Libertine” container, and some Android apps via “Waydroid.” And Volla has an excellent track record of delivering on their product promises - in contrast to Purism.
