pictures dont do that blue any justice. Its awesome and I would do some serious things for a TKL version. I had one and ended up selling it because it was too long.
You know I learned to appreciate the ten key part when using Unicomps and IBMs. I program them for 2 layers, one is standard ten keys and one is macro part (fancy stuff in Vim). I switch between them using numlock key.
Also I found out that I almost don't use mouse during the day. I use Vim for development works which is awesome without mouse. The rest of OS X is pretty fine with keyboard too, especially when you install BetterSnapTool for tiled window management and Vimium/Vimari for mouseless web browsing. Of course mapping Caps Lock to Control is a must.
