I don't get the obsession with custom keyboard with ever fewer keys. If I designed one, if anything it would have at least a few more modifier keys that a standard keyboard.
I don't get why most keyboards available in stores have a numpad. I never use it, and it takes up valuable space on my desk. I wonder how many people actually use the numpad section of a keyboard on a daily basis.
I’d say most analytics focused people will need to do something like this at some point - that, and people who are forced to interact with spreadsheets occasionally.
