I don’t have a problem with the low resolution but the contrast on that is absolutely horrendous. It’s almost impossible to see which pixels are lit and which aren’t in bright lighting, and that’s even visible in the OP’s post.
Additionally - and I don’t know if it’s part of the charm - the space between adjacent pixels being as wide as a pixel itself also limits the ergonomics of the display in a way that a similar resolution but more tightly spaced display would be more usable.
The pictures in the article really aren't doing the display any favors. I own a Tidbyt and the contrast is way better than it appears here, and the brightness is adjustable (with an API call if you want!) with a pretty high max setting.
