Because the FLOSS philosophy gives you all the options, while Windows
and Mac OS X don't.

Works fine here, with or without an RT kernel. But I use Debian, not Ubuntu.

xruns can also come from hardware that seems to be unrelated to audio.
For example, a laptop's wireless network driver that frequently checks
to see if there's a wireless connection to make, even when the wireless
adapter's antenna is turned off. (Mine does that. I guess the real
option there is to blacklist the wireless driver.) Or shared hardware
interrupts. Or the presence of binary blobs in the kernel, like NVidia's
proprietary driver.
