A few pictures of my own (The things on the sides are the rubber feet; I took them off the bottom so it didn't wobble when it was half hanging off the edge of the desk)
I've been casually using the keyboard for a few hours now, and here are my thoughts thus far:
This list is disproportionately larger than the good, because they already tell you most of the good things. You have to figure out the bad things by using it. I decided to call these "what could be improved" instead of "the bad," because none of them are really *that* bad.
I haven't done a ton of typing on the keyboard yet, but I have typed this page on it, and overall, it's not very hard to get used to. I do make mistakes fairly often, like hitting tab instead of "b", or confusing the x, c, and v keys, but I can't imagine that it will take very long to get back to normal.
The HardwareCentral review reported to have a hard time adjusting to the center backspace and enter keys. I expected that to be the case, and I have reached for the old spots a few times, but it was actually pretty easy to get used to the new locations. They also reported having a problem with putting their hand in the wrong place on home row for 3 days - wow! I can't say I ever had that problem, as I tend to never look at the keyboard, and I use the little bumps on the f and k keys to position my hands. From the comments they make, it seems like they might not be touch typists, which I imagine would slow the learning process.
The keyboard is pretty much what I was expecting, which means that it's worth $100 to me. I probably would have even paid more for it. Hopefully the typematrix people are selling enough of these things to stay around, and hopefully they can make even cooler keyboards in the future!
Do this at your own risk! You're probably voiding the warranty.
(Forgive my lack of a digicam)
I wanted to swap some key caps, but you can't see under the keys, and it felt too risky to just blindly pry them off without seeing exactly how they attach to the keyboard. So I took the thing apart, which was pretty straightforward. There are 8 philips head screws on the bottom holding the keyboard together, and two smaller ones in the middle holding the middle strip in place. Unscrew them all, and the top half of the casing pulls off. The electronics are screwed into the bottom piece of the casing, and the keypad is attached to that via two ribbon cables. The keypad is metal on the bottom and plastic on top (you can't really take them apart), with the circuitry sandwiched in between.
The key mechanisms are kind of interesting; they're definitely different from your average keyboard. They call them "double scissor" keys (">image), and I assume they are what's used on laptops, since the typematrix basically feels like a rearranged laptop keyboard. The keypad didn't appear to have a rubber membrane, it seemed to have individual little rubber nipples under each key.
Anyways, to get the caps off, you basically just tug at the top and the bottom, and the two little clips on each will pop off. I did the bottoms and then the tops, but I doubt the order matters. The larger keys have the metal stabilizer bars too, so you need to make sure and get those back into their grooves.
Having Home/End/PgUp/PgDn relegated to Fn-keys is unacceptable, but thankfully, I don't use the F9-F12 keys at all, so swapping them fixes the problem. The following xmodmap code will swap them around:
keycode 75 = Home keycode 76 = End keycode 95 = Prior keycode 96 = Next keycode 97 = F9 keycode 103 = F10 keycode 99 = F11 keycode 105 = F12
You have Shift, Control, Alt, Super ("start" on the keyboard), Menu ("application"), and caps lock -- imagine what ridiculous key bindings you can come up with, now that you have all of these available! (Ok, maybe I'm the only one imagining it)
I'm pretty sure this is supposed to be the "menu" key, but who cares about the menu key; we can make it another modifier! I decided to make it Hyper_L and mod3. You need this xmodmap code:
keycode 117 = Hyper_L add mod3 = Hyper_L
You also need to execute this to turn off repeating on the key:
xset -r 117
