This is a quick recommendation for the XP-Pen G640 drawing tablet, for those fellow Linux users who like to do a bit of a scribble. It costs a penny shy of £40 as I write this, and it works flawlessly out of the box on Ubuntu 18.04 and 20.04 with no drivers or any other fiddling required. Just plug it in and go.
This is a great little tablet for doodling, whiteboarding in the working-at-home era, pwning noobs on Skribblio and generally messing about. For all I know someone might even buy one of these, download Super Street's car colouring pages, fire up MyPaint and burn a few hours in the evening when lockdown gives them nothing better to do.
I shall give a necessary disclaimer that I occasionally doodle stuff just for myself (it helps my concentration in read-only tasks, and when I am in deep thought) and that I am not an artist at all. If I was I might want something like a few dedicated buttons for commonly-used operations like undo and erase. And I'm sure that in many other ways, someone using this for actual artwork would find this vastly inferior to things costing several times as much money. But for me, this cheap tablet works great!
