Very nice! She is a very good speaker. I want to add two things:
1. A gentleman at the end says he's learning Colemak and that he's forgotten QWERTY as a cost. I type Dvorak every day, and I have to refute that claim! Sure, Colemak is a lot closer to QWERTY but I have a hard time believing he actually forgot QWERTY. So don't worry about that, I encourage you to try a different layout (and recommend Dvorak for its prevalence in the wild.)
2. There is a second gentleman asking if this could be done for iPhone. Such efforts are underway, I know there is some project at KTH doing this. It doesn't really work all too well but it is a nice concept. Perhaps if you could also properly see the screen while typing...
I have used Dvorak fulltime for about a decade and I'm much worse at qwerty than I used to be. I can get back up to speed, but it feels like reciting a poem I used to know and I can't actually think about what I'm doing.
I think it's about how often you switch keyboards. I switch between Windows and Mac keyboards daily (work/home) and now I rarely make a mistake when trying to use a shortcut. Same thing happened when I was learning russian keyboard layout, at first I wouldn't be able to switch despite knowing both layouts. Now I talk with two people simultanously, switching between russian and english (qwerty) every sentence
Here is my experience with Dvorak and AZERTY (the French variant of QWERTY). I learnt AZERTY as a kid, then learnt a French dvorak layout, and then learnt the US dvorak layout, which I now use.
I have totally forgotten the French dvorak, but not AZERTY, because I feel I haven't learned those in the same fashion. AZERTY I learnt by hunt-and-peck (I was around 50-60 WPM when I switched), the dvorak variants as touch-typing (as the key labels don't match what's written on the keyboard, so you have to do it this way). So my feeling is that if you used to hunt and peck with QWERTY, dvorak will not overwrite this; otherwise, there's a risk.
This is also what I think is the main benefit of learning an alternate keyboard layout: force you to touch-type properly. Some people manage to move on to proper touch-type on a keyboard layout they learnt by hunt-and-peck, but others don't, and the level of comfort achieved by not looking at the keyboard at all is really, really worth it. Glancing alternatively at the keyboard and screen is stressful and causes typos.
By contrast, if you can already touch-type proficiently in QWERTY (but really touch-type), then I think the benefits of learning an alternate keyboard layout are less clear. My impression is that it saves you maybe some muscle strain because your hands move a lot less, but I'm not sure of how beneficial that is.
I'll second that on Dvorak. I have very little trouble moving back to QWERTY. I typically make a few mistakes only for the first 1 to 5 minutes after the switch, but other than that I can type in both layouts without even thinking about it.
Same. But if I am going to be at a computer for longer than a couple minutes, usually dvorak is in the keyboard layout options so I can just change it to that.
For anyone who has taken the time to learn Dvorak: From the point you began to learn it, how long did it take to become more proficient at Dvorak than QWERTY? How much more proficient do you consider yourself to be at typing as a result?
Took about a year to work most of the mistakes out. Lots of typos. An unimaginable amount of typos. I don't consider myself any more proficient. Typing dvorak is a bit different: I type word by word, instead of letter by letter. I still type on qwerty (who doesn't, at work?) but that feels more like stringing together an infinite sequence of letters. Dvorak tends to make words a bit easier to type in single fluid motions. So when I actually start typing fast in dvorak it gets crazy fast pretty quickly. Hence the typos.
It took at least a few years before I could type dvorak with just my right hand, which is tricky seeing the other letters when I'm staring at a qwerty keyboard.
It took me a week to get to 70wpm or so. I can do 100+ sustained now with not much fatigue. I had been getting hand pains in qwerty, so I switched completely during a paper in high school and haven't looked back.
I can type nearly as fast in qwerty as I used to, but it is uncomfortable, awkward, and I do make errors often.
