I'm using a Pok3r and the programming is great for remapping keys - I definitely need Ctrl on Capslock. I bought it because my Unicomp was taking up too much desktop space.
To get to the point: Even as an Emacs user I am missing the arrow keys and Insert and Home. Tenkeyless is better.
So for me the above keyboard wouldn't be the ultimate hacking keyboard.
I dual boot Windows and Linux, and remapping on both platforms consistently (incl. system updates, etc.) is a pain in the ass. I also need to use a remote desktop connection with a normal keyboard from time to time, which makes the software solution even more annoying.
Same here (just with a different keyboard). Plus you can establish a few mappings more and get a minimalistic "Vim layer" going that works everywhere (say mapping caps+w to ctrl-right). That's great if you're stranded in Windows and have no options to opt for Vim-like input on almost all text widgets.
