I started to fill it in but many of the questions either do not have appropriate choices or do not make sense.
I'm noting these not to criticize but in the hope that they will help you make your survey better.
Question 4 asks the user to choose 2 options, but for me only one (other) applies. Choosing another would be a lie.
At home my service is provided by cable, which is not an option for Question 5 ("How do you connect to the internet at home?")--and there is no "Other" option.
For Question 6, the correct answer for me would be "I run multiple OSes"--except that this option continues on to say "using virtualization technologies". While I do use virtualization, I also use boot managers, plus I have several computers, some of which run different OSes.
Question 15 says to pick only 3 choices, which I would not be able to do truthfully since all apply to me.
Question 26 has nothing to do with the choices given (but I think that this may be a language issue).
Many of the options should have "Other" options with corresponding text inputs.
Anyway, these are mostly nitpicks. However, I cannot complete the survey as it is and tell the whole truth either, so for now I will leave it alone. I wish you good luck with your survey though!
