Honestly, being a casual Linux user, sound card support is not the defining factor holding back Linux adoption. While Ubuntu goes a long way to improving the user experience with Linux, even to get it to a 'standard' setup, I needed to use the console no less than 5 times. That's *needed* to, there was no GUI way to do what I was trying to do.
While I personally have no problem doing that, I shudder at the idea of talking someone like my father through it. The day that I can combine Linux stability with ease of use... that will be the year of the Linux desktop. Driver integration and support goes a long way to doing that, and a flushed out menu system will put it over the top.
What does your father do that requires editing configuration files or using a shell interface on Ubuntu 8.10?
