I have backspace on my left thumb: https://www.kinesis-ergo.com/shop/advantage2/ https://www.kinesis-ergo.com/shop/advantage2/ Highly recommended for Linux or Windows desktop computers if you have RSI trouble. A bit unwieldy for laptops though. I use both and switching isn't a big issue (unlike switching national keyboards, which drives me crazy). It doesn't quite have enough modifiers for Mac - can't have both left and right versions of shift, alt, ctrl and command. Vi users have to swap the up-arrow and the down-arrow since they use the same fingers as j and k, but reversed. However, it's pretty easy to remap, and it happens in the keyboard so it works everywhere.
