First off, I'm by and large a full-time Ubuntu user. However, I'm also one of their most vocal critics for becoming so detached from their core market as well. In response, I have used both operating systems and it has been interesting to see how each deals with the issue of usability for the casual user.
The PCLinuxOS Approach. When I started off looking for support from their wiki for my NVIDIA card, I ended up using the search box as a means to locate the support I was looking for. Why this was needed remains beyond me, but this is hardly the only distro to show this fault.
A fast search for NVIDIA brought me to this page . Great! This is exactly what I was looking for, it's just a shame I had to 'search' for it rather than logically adding it into their quickstart guide.
The Ubuntu Approach.
