You definitely spend more time when you touch two keys "Shift + 7" to type the *, than when you type just "1".
I doubt this. Hitting SHIFT + 8 is much easier and less awkward than the pinky hitting the "1".
And this is assuming everyone has a US keyboard.
You can be sure, everyone has. And numbers are Arabic. Not sure about the *. But, layout is the same in each culture.
No, layout is different in each country. My personal laptop is mexican and my work laptop is american. I usually have typos due to the different layouts. That happens as well in Mexico because we have 2 different layouts: mexican and latinamerican.
I've also used a french keyboard which needs Shift to enter numbers.
