Really?  I gave Ubuntu a go as a daily driver a few years back.  Getting WiFi working was a struggle, the constant offers to install apps in normal browsing flow was irritating, sound died a few times, and over time my boot partition got filled up with old linux images and had to be cleaned with magical command-line incantations.<p>That being said, it had less trouble with my network printer than Windows does.<p>I get the appeal of Linux, but I did not have a grandma-friendly experience.
