Single sentence description:
Colemak is a keyboard layout that allows to type faster, ergonomically and comfortably using your existing keyboard.
Full description:
Colemak is a modern alternative to the QWERTY and Dvorak layouts. It is designed for efficient and ergonomic touch typing in English.

• Colemak gets rid of the Caps Lock, and replaces it with Backspace. You no longer need to move your hand off the home position just to correct errors. This alone saves about 15%-20% of total finger movement.
• Colemak places the 10 most frequent letters of English on the home row.
• Colemak has been designed to be easy to learn for existing QWERTY typists. Most of the keys remain in their QWERTY positions.
• Colemak takes into account many ergonomic factors: finger distance, finger balance, finger strength, hand alternation, uncomfortable finger combos, etc.
• It can work with all standard keyboards, including laptops. It is available for Windows/Linux/Mac and many more operating systems.

Colemak looks very nice, though I wonder if there are not more optimisations to make, e.g.:

• Moving the Backspace down to above Enter
• Moving ; and ` off the home row and putting more commonly-used punctuation there

Minor ideas. Colemak gets a +1 from me.

It's a crazy idea - replacing CapsLock with a much more dangerous key…

Where is the "Delete" key? ))) Will the functionality of Ctl-Alt-Delete be replaced by something else, like Ctl-Alt-Backspace? Will you be abe to convince the software and hardware manufacturers to correct their documentation?

C'mon, actually try it out people, the keymap file is available at the Colemak website. Typing on it is very natural, the keys you need most are easy to hit,
but many of the keys are not changed so it is easy to learn. In just a few days on it I am gaining speed rapidly and can tell that my hands don't have to move nearly as much.
Unlike Dvorak, the ctrl-C, X and ctrl-V shortcuts are still in the right place. And backspace being hittable without moving the hands from the home row
(by putting it at capslock) makes for much easier typing.

Even if you aren't willing to learn a whole new keyboard and want to stick with QWERTY, give at least the remapping of Capslock=backspace a try.
Just that change makes typing a lot easier and reduces hand motion a ton. That alone could save you getting RSI.

cut below and make into a .reg file: or get it rom the Colemak site (this will ONLY make capslock a second backspace)

REGEDIT4

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Keyboard Layout]
"Scancode Map"=hex:00,00,00,00,00,00,00,00,02,00,00,00,0e,00,3a,00,00,00,00,00

[HKEY_CURRENT_USER\Keyboard Layout]
"Scancode Map"=-

How does that work for other languages, like Spanish or French, Polish, or Scandinavian languages? I mean the most requently used letters, and frequent letter clusters?

Letter frequencies will impact the efficiency of a layout but more needs to be taken into account to achieve a comfortable keyboard. Keys need to be remapped to make typing of letter combinations comfortable. Given that asdf is much easier to type than fdsa, you would not want, for example, to have a home row that had asd replaced by the reverse of the most frequently appearing triplet (which is "the"). While keys on home row are by far easier to access than the boonies of the Z and Q, the exact mapping of characters to effort-equivalent keys needs to consider stroke path.

Take a look at my X-Fu submission which attempts to address this.

It’s a shame not too many people know about this keyboard.

Good job making this keyboard, Shai! The way you present Colemak on your site is superb. Colemak definitely gets a plus from me.

Hey, I gave your keyboard keyboard convert a try over at http://colemak.com/ I think that after a while I could get used to it. My question for you and Martink, Leizoor, and Qwertie is: if you're going to rearrange the letters on the keyboard, why wouldn't you place the E under an index finger? I like your choice of letters for home row, and other than the E, I like your choice for the other letters my index finger hits, but none of you has placed the most used letter in the English alphabet under the most easily used finger. If you transposed N and E or changed NEIO to EION, I think I might actually prefer your design to the qwerty.

Sorry to criticize. If there is a reason, tell me. I'm not much of a typist, so I might be missing something.

I wish there was time for me to enter a design of my own. Maybe next year?

Gratz on winning, it's a great layout in terms of the classic keyboard feel, nice work and happy new year!
