I'm not sure if it is just me, but when I write, it has to be on a specific keyboard. I just can't get into the flow of the words until unless it is that specific keyboard. I started out 10 years ago with the Sony VAIO island style keyboards, then got into the MacBook Pro keyboard (the chunky one) and now the butterfly switch keyboard on the MacBook Pro. For each style of keyboard I used it for about 6 years. And once I get used to one design, I have to stick to it for at least a few years to write.
Anyone else has that feeling? What's your keyboard of choice?
