In relation with this question at SuperUser, I also want some user feedback about this topic.
So you install a desktop application which you've just bought/downloaded/pirated and you start it up. You look at the screen and you're start having questions about the application...
Will you press F1 first to get the context-sensitive help or would you rather read the online/hardcopy/ manual/PDF?
This is something I wonder about and this is a bit subjective, so instead I'm going to ask something different, to all of you who develop desktop applications: Do you (still) want context-sensitive helpfiles? Would you stop using an application if it has no context-sensitive help?
Yes, or no, please. Feel free to add some subjective texts but to me, what is important is knowing if modern users are still relying on context-sensitive help for their GUI applications.
Personally, I rarely use context-sensitive help and just start exploring.
