Well, I don't generally feel as if the few stutters I just heard in a cbs news 
story I just played were anything but dsl glitches here. xmms, playing high 
quality (Q7) oggs from my own drive are dead smoothly done.  nbc did want to 
let me play anything because I have adblock enabled, and neither did abc but 
their anims played nicely, fox news smoothly played everything I clicked on.

The only problem I've had so far is with a proprietary daemon from belkin, 
which took about 10 kills and restarts after I'd booted to 2.6.21-CFS-v6 
before it quit wanting a steady 40% of the cpu when it was running.  Now it 
only does that when the bulldog gui is running.  That's not normal either, 
but getting fixes out of belkin is like breeding elephants, lots of yelling 
and screaming and it takes 22 months to get results.  My next ups will NOT be 
a belkin.

X is not reniced here, but I did run kmail up to -5.

Compared to mainline?  I still think this is a 100% keeper for desktop users 
like me.
