High prices are driven due to price of screens and the amount of support we provide. It's a development kit, intended for customers building products. We're not that much of DIY (like a hacked Kindle or the OPs solution), but rather a production ready solution that you can use to prototype and later deploy in field. Examples [1], [2], [3]:

- wastedhours 10y agoReally interesting product selection - obviously on the pricey end when the market here is looking for hacky project type prices, but an open version of Joan for people to get playing with your stack at that £299/$350 price point might work for feeding dev support further up the chain?
- luka-birsa 10y agoWe tried that previously, but it didn't work out. People that want a cheap version, still complained about the price and suggested a hacked Amazon Kindle as a viable alternative.
- wastedhours 10y agoFair enough! Though if you ever did want to explore that again, I'd be interested in a more entry-level to prototype some signage ideas (email in profile).
