They ran a Kickstarter last year with a target ship date of late November, but I’m not sure how many orders they’ve filled. None of my friends who ordered have received theirs.
Their open source repositories are available here: https://github.com/cutiepi-io
Note this isn’t a tablet in the traditional sense. Think of it as a Raspberry Pi with external touchscreen, camera, and battery folded into a tablet-like form factor. They’ve done some cool things with software and hardware to bring it all together, but it needs to be viewed as hackable open source hardware and not a competitor to a cheap Android tablet from Amazon.
