I now have a production model with the white clicky keyswitches. Ultra happy with it. I've been using Kinesis Advantage2s for a shade over two decades - the same model DanielDK used for a long time. The Glove80 is simply better. I prefer the clicky keyswitches. Ergonomics are great. It's really repairable - everything is held together with screws (spare parts for my Advantage2s are not available, and the function keys are not repairable). Open firmware so you can make it do wacky stuff if the need arises. Small and light enough for travel - I should get a proper case but it's survived a fair few trips stuffed into my backpack.
Yeah, adaptation to new keyboard layouts is hard. I used a layout that mimicked my old Advantage2 - so I'd paid the cost to learn columnar already. I found the default Glove80 layout was better, but switching meant a month of confusing Ctrl and Shift. All better now!
