Can't comment on IBMs but programmable keyboards have been a revelation. I thought 34 key keyboards were a joke but after getting a ferris I now have layers for numbers, symbols, navigation and media all under the home row with home row mods. I don't have to stretch for anything any more. I think a concave ferris with 3 thumb keys or an extra outside column would be the sweet spot, or a more staggered corne.
