One thing I’m trying to get better at is quick sketches – this is important for effective communication and documentation on distributed teams. After researching graphics drawing tablets, I ended up purchasing a XP-Pen Deco 01 some time ago, available for $67 at Amazon. It works out the box with my MAC and Arch Linux boxes, which is the main reason I got this model. It seems the more popular Wacom tablets are not as well supported on Linux. So far it has performed well, and seems more than adequate for quick sketches I do (see examples below from recent blog posts).
I have always been looking for such tools, although it would be one step up if it converted it to visio like diagrams
