Not for me it isn't!
I am a Linux user and now and again I have to help out the Vista members of the family.
I can't even find my way round the interface in vista!
Ubuntu is easier to install than windows, as it's quicker!
As regards help from forums, there is enough info for most people to learn the basics, as you did with windows at one point, and buy kit that will run Linux.
If you buy windows only kit (really cheap) then you'll have to run windows.
Most of the kit that's runs on Linux runs better on windows as well.
I'd say Linux is for more advanced users who have grown out of windows and lockin and now want to learn more about computers in general.
