My dvorak speed is fairly fast but not as accurate as most, but I've never taken a test on it.

My experience with dvorak is that alot of the combos feel natural but a bunch of them don't
and really grind the finger joints at really high typing speeds, I was noticing some
finger joint pain and tingling from certain offenders I type regularly and fast,
friends being a good example of something that strains all the joints when
your trying to type it to fast almost ensuring all fingers will have to reach bad keys on
the right hand, grinding the finger joints LRLRLR.

The "F" key alone might causing most of my problems, extreme lateral movement is bad,
especially index to pinky.
So far it seems that Colemak doesn't have some of the left to right extremes I've seen on Dv.
Seems like fingers reach further better the  lower on the keyboard a key is,
colemak "B" isn't really a issue like dvorak "F" is.

I decided to switch to see if it is better on this layout and to get better symbol key positions,
especially most of the braces.

I like the easier bracket ("[" and "]") access in colemak and qwerty rather than then the very top row placement.
In qwerty / colemak all the programming brackets are close enough for easy enough regular use,
slightly harder <> brackets (still easy enough) but easier [] brackets, and I can hit the () brackets without too much trouble,
but Dvorak [] is way out of the way, for stuff like dictionaries, althouth = is now in a worse spot.

Dvoraks bad F key placement (index finger), heavy use of the right pinky and heavier right hand usage, seems
to grind the right hand finger joints when typed fast.

Figured I'd give it a go and see if the few things that annoy me about Dvorak are better on Colemak,
as well as it in "theory" is slightly more efficient then Dvorak, figured I'd give it a go.

I'd like to see a programmers colemak (might have to mod one for linux myself) come out,
with atleasted inverted shift keys for 1 - 0.
It'd would be much nicer if it was some "official spec" though, be alot more likely
to get into stuff out of the box.

After using Colemak for a year, I still haven't made any progress with it in terms of accuracy. Accurately I could be typing so slow. I like the way that punctuation is split on the Dvorak keyboard and by the looks of it and by personal research, its better for typing code; but when chatting with someone online, using ":)" & ";)" would be a bit awkward as compared to Colemak.
All in all Colemak is the better option for an average computer user, but for a coder, I'm not too sure. It does score low in the comparison tests.

When it comes to the punctuation, Dvorak does have the advantage there. However when chatting online, stuff like ':)' or ':P' becomes a bit of a pain or a hassle. But something to get used to I guess.

When it comes to the shortcuts, Colemak absolutely shines. Now it should be noted that ZXCV in Dvorak are in better positions for typing. If you wish to use these shortcuts with one hand in tandom with mouse, on Dvorak, you need switch the mouse to the left. That makes a whole difference. The setup is far more ergonomic than with Colemak IMO.
But, on Windows those shortcuts are a bit of a pain. The Ctrl button is quite a stretch if you don't have long fingers. On a Mac, you will have no problem with those shortcuts on Dvorak; since you use the command button with your thumb. I have no idea about the Linux issue, but I would guess that you could remap the keys much like the mac with relative ease to make full use of that.
I fail to see why Colemak isn't recognised by MS Windows; even though it makes using their OS much, much better. Kinda shows how backward MS is afterall. (That's something of a different matter).

People who use these shortcuts mostly use  MS Office programs and Graphic Designing software. Basically most people who have been using computers for a while know these commands. Using them with one hand in tandom with a mouse, makes work quite a bit easier and quicker. Once you get used to it, you'll wonder how you managed without them. :P

I agree on the 'F' key, I disagree on the 'L' though unlike most dvorak users I think 'L'
is actually on a finger that is easier to hit the upper row on then the index finger hitting 'g'
if using a standard keyboard shape, I'm completely okay with the 'L' keys placement.
I don't have a issue with the ';' which isn't used much except special programming commands
usually to end a line, or like you said chatting online, its used as much as its position
in the keyboard layout deserves and I don't find it to be in a bad position to hit when I actually use it;
Even ocassionally using VI I don't find the ':' to be hard to hit I actually like the left hand pinky hits shift, left hand ring finger hits ':' feel to it.

Colemak puts the 'L' on the upper row of the index finger, and while I was testing that out,
it felt far more un-natural then having it on the right pinky, I was suprised with that.
After all the pinky is a short finger, the only thing I could come up with is that the pinky
is usually angled higher in its resting position with common hand placement.
Unless you're using a ergonomic keyboard.

Maybe I've been typing dvorak too long but I like the 'L' position.

Really anything on the upper row above the home position, is a easy enough to hit key though.

Most Colemak users I've seen on this forum won't try to persuade you that Colemak is perfect. In my experience though, it works very well and has stood the test of some time now. If anything's better it's probably better for some and worse for some as preferences do play a large role when hunting perfection. In other words, Colemak is a perfectly good alternative if you want something with a supportive community, even if it can't be perfect for you. I believe that the potential for further benefit for most users is minor indeed, but that's just my feeling about it.

The non US bottom left is a bit awkward.  I've got my pipe back slash and colons there (Dvorak) and it took a while to get used to.  I think the tilde is down there with standard Dvorak.  There's some difference for me when moving from Mac to Linux anyway, which probably adds to the confusion.

I don't like Dvorak's P (Qwerty R) that much either.

As Davkol mentions, is that one handed shortcuts using chords on the bottom left of the keyboard can contort the hand, look at your hand as you do it, there are probably better ways to tackle it, but for me it's weird.  I mostly try and use a modifier on one hand while I select the other key on the other.  Sticky keys also give a much more relaxed feel to using the keyboard - it lifts those twists.

Perhaps Qwerty->Dvorak->Colemak makes for a somewhat harder transition.

@Knightjp, you just won't let go of those one handed shortcuts...

I've mentioned the p before.  With Dvorak the vowels are on the left hand and only a few consonants: p (r) and qjkx (xcvb) - brackets denote Qwerty's corresponding keys.  The p has a higher frequency than the other letters.  Touch typing guides suggest you use the index finger for the p (r), but to do so comfortably you need to slide the hand to the left, rather than angling it.  Try Shift + P and Ctrl + P (dvorak and colemak) on the same hand.  It's nasty, see how you orientate your hand.  Using the left middle for that key might be a better alternative (crappy left side stagger on standard keyboard).

@pinkyache.. LOL... Yeah I kinda like them. However on a mac its a better than using the Ctrl button. I understand about shift considering that some don't have the long fingers that I have. :)

@DreymaR... Lol.. thanks for that. :)
I suppose using sticky keys will make using the shortcuts with one hand on Dvorak a whole lot better. But I like the feel of them on Colemak.

Maybe I should invest in a mac keyboard for my PC then (its usb right?).

The position of the control key has annoyed me for years on the standard pc keyboard.

I'd have more bindings for mmos if I could hit control with my thumbs. >:)
