I use those keys heavily, and was hoping they'd fix it in the 16. Sadly, no. Their keyboard connector layout seems to make it difficult to have a keyboard with more rows, so having a layout with the bottom 3 arrow keys in a new row seems unlikely. But what about a touchpad module that has 3 (or 4) arrow keys on it?

Still, it's not a complete nonstarter for me, because the 16 does have that optional keypad. I could actually start using the numlock key again.
