Oh yeah, totally agreed, I absolutely love how the arrow keys work on HHKB. I would be lying if I said there wasn't a learning curve to it, however. First few weeks, i was definitely missing the correct keys, but once it got into my muscle memory, it became great.
Using your right pinkie to hit function and then having the arrows right there is nice. I also use caps lock as control and it’s nice to have it as a hardware default in the HHKB too.
