(and in case you're wondering, I did this just now on a keyboard as you describe in my school's library (that's why the desktop is so generic and Firefox is open, not Google Chrome).)
I'm not claiming to do that constantly, however. I probably could, but after doing a few more tests and races on that site with some very devious word choices (type "appropriate" twice in the space of three words? Yeah, no thanks.), I've found that I usually hover around 90-100 words per minute in day-to-day typing. It's a lot more relaxing than engaging the turbo all the time, which cramps up my hands after a while.
I think it depends a lot on how you were taught to type (if taught at all), because when I learned to type in elementary school we were always taught not to look at the keyboard, so I don't when I type, and I'm sure a fair amount of people do not as well.
None of us come CLOSE to the speed typists in the early 20th century, though. I was shown a video in one of my classes at one point of a speed typing competition from something like the 1920s, where about twenty typists or so would pound away for minutes on end on typewriters (a LOT harder to type on than keyboards for those that don't know...and there was no backspace so you had to be perfect.) at something like 150 words per minute.
