^ That's it I am now using Linux

The masses you are talking about has problems using Windows too. A geek will notice that the reason the print output is poor or not working is because of Ubuntu's lack of driver support, another person will almost certainly not. Despite mass adoption and all that stuff we are still not at a point where users can 'fully' play and work with
Windows out of the box. I still get questions about where to plug in the USB, and not only from grandparents.
What I am getting at is the entry point to computers is still an open entry point. If a Linux loaded computer is sitting at a shop and the customer has some familiarity with (through marketing for example) it then it has a chance and the person wouldn't know the difference between 'no linux driver support' and 'windows BSOD' when something doesn't work
