no, i'm going to look at the x developers and system integrators and say, "can 
you please write and configure touchpad devices to work as well as they do in 
Microsoft Windows?" i won't even ask for Mac-level competency.

it's shocking how much better the touchpad works in Vista versus OpenSuse on 
my son's laptop. SHOCKING.

as someone who is now working for a distro, perhaps you could help raise 
awareness of these issues as opposed to trying to get upstream to neuter the 
user interface. :)

ugh, let's cut the "auntie Nora" crap. it's based an an ageist, sexist and 
highly irrelevant stereotype. let's talk about HCI as a real topic.

"magical" pagers and taskbars behave identically; roll up a bit and you're 
back to where you were.
