Until the Linux kernel gets everything all situated out I think one of the big things that distros can probably do to improve user experience is provide Desktop/Multimedia optimized kernels.
Normally I am a big fan of 'do one thing and get it right before worrying about features' approach, but it's irritating to have to recompile my kernel to get proper responsiveness because the kernels from Debian are all optimized for server use.
$ grep -i preempt /boot/config-2.6.*

/boot/config-2.6.26-2-686:# CONFIG_PREEMPT is not set

I mean, seriously.. How long has Preempt support been around? *cry*
