Indeed. I well remember spending $150 for a ThinkOutside folding bluetooth keyboard and mouse for my PDA in 2005 and thinking it was the coolest thing ever. Shame you can't get a modern folding keyboard with that build quality.

I might even still have my ThinkOutside lying around somewhere, but the keys were getting a bit sticky for some reason. There is something about that market that I'm obviously missing, because I'm astounded that no one has cloned the thing. Though I don't have the use case for one that I used to, I'd still spend the money again. It is such a cool little device, I'd find something to do with it.

I think it's relegated to low-volume hobbyists. e.g. this is low-profile, wireless, and looks well made. https://lowprokb.ca/products/corne-ish-zen

I tossed mine for the same reason. I believe the fact all the keys are depressed when the keyboard is folded causes the rubber domes to permanently deform after years under compression.
