HHKB is a great keyboard (it's my personal choice of keyboard too, I love the Unix layout), but it's a 60% keyboard not a Ten Keyless, it sounds like the GP has a need for function keys.
Yep, function keys and mostly also the arrow keys. A full keyboard is too large but I need the extra arrow keys. (Ironically, I work in Emacs most of the time but I need the arrow keys in other applications.)
