I'll bite first, don't want to turn down the opportunity to give input when it's being requested.
1) I may have used the PDF version when I first started using CodeWarrior, but it was limited at best. I have never printed out any of the documentation. The last thing I need is more documents cluttering up my work area. The only time I would have considered printing it out is when I first started to use it if I had wanted to read it straight through or for an extended period of time.
2) When I do need to use the documentation I usually use the Windows Help version finding a keyword in the index or using the search function if that doesn't work.
3) I have never used the tooltips and turned them off soon after installing them. Looking back at some of them, it isn't that they aren't useful, I just turned them off out of habit. I get annoyed by pop-up boxes when I open an application.
