yes it could worth it but it also worth money lol
curious about lettering on dark grey colour, is it readable from dark?
can we switch return by enter through DIP switch
imho, hhkb is definitely worth the money - but if you decide to buy one, make sure you give it a couple of weeks to break in.
There is a DIP switch combo for Mac vs PC - I think if you switch to PC mode, you should get an Enter for the Return key.
From what I heard about the dark grey lettering, they are barely legible in bright lighting - think of them as ninja keys. There are nipples on the F/J keys so touch-typing in the dark is a non-issue. I personally use a blank white hhkb - even though the font on the white is absolutely beautiful, they really aren't necessary. Also with a blank board, if I ever decide to invest the time to learn Colemak or Dvorak, keycaps are a non-issue.
ymmv, but the people who seem to get the greatest benefit from a hhkb are UNIX-programmers who happen to be
touch typists. The control-key is in the perfect place for vim/emacs. The small form factor allows one to keep fingers on home row. Its lightness and portability is perfect for remote ssh/VPN access via a laptop. Laptop ergonomics are improved by the external keyboard. Cursor/function keys are within easy reach. imho, I cannot imagine an improvement on hhkb except possibly the addition of Bluetooth, but even then, requiring batteries is a bit of a trade-off. Even though I love the idea of a programmable hhkb, it's so good already that I can't bring myself to take the risk/effort to mod the board.
Of course, it's the thocking that really makes Topre unique, and many non-developers will like a hhkb just for the touch-and-feel of the keyboard.
It is the least fatigue-inducing switch out there and arguably, the board that is the most fun to type on. But for non-UNIX-programmers, there may be issues: for example, crazy multi-key combos may be needed for Visual Studio, which I haven't used for years, but maybe other developers can chime in here.
Some people who are bothered by the Fn-arrow key combos may opt to get the JP version of the hhkb. I think it's a non-issue as the Fn-arrow only took a week to get used to and most of the time, I am using vim-mode provided by utilities or the OS.
EDIT: So many of my friends laugh when they hear that hhkb stands for Happy Hacking KeyBoard, but the more I use this board, the more I feel that the name is perfectly apt - as perfect as the board itself!
