Printing out and using a biro is usually a concession accommodated in the design phase when someone like me says that most respondents won’t be able to use the form as intended but someone up the chain is wedded to the idea and will hear no alternative. Using a biro on your screen is not recommended.
I can’t say if they’re widely used or not, I would have assumed some kind of easily deployed web form would be to hand, but that wasn’t an option on the project I was involved with.
Adobe would say yes. I would disagree. If you open it in Acrobat Reader it will likely work as the author intended but a lot of alternative PDF viewers don’t support the full functionality the standard offers, so the reality is PDF is rarely the right tool for the job unless you can control the device the form is being filled out on.
