Glad to see another endorsement of the Tex Beetle. I get the sense that its developer is striving to make a high-quality product, and that future models from his company might be even better. The main thing holding me back is that I like to mod my keyboards by replacing dark keycaps with two-tone beige and gray with black or blue legends, and the Beetle has a number of non-standard keys that would be difficult to replace. Any thoughts on sources of keycap sets for the Beetle?
Another issue I have with the Beetle is that although it has dedicated arrow keys, there are some changes I would like to make in the Fn layer to make it more intuitive, at least for me. However, I think that Tex might be coming out with firmware downloads to change the layout in various ways. The company has definitely been receptive to customer feedback, and I notice that the Beetle has been adopted for redistribution by Qwerkeys in the UK.
The Beetle does look like a solid product, and the more I see positive recommendations like yours, the more I am inclined to give it a try.
