Hi Tom,

If I can scrape together enough money I'm going to upgrade my
laptop to 512 MB of ram but I am an illegal alien living in the Czech
Republic who has spent most of the last 5 years hitch hiking and being
a pseudo-vagabond - pseudo entreprenuer so every euro penny counts. 
BTW I'm on a Toshiba A10 2.2 Celeron laptop.

About Windows, the boot up time is irrelevant to me.  My main
concern is application startup time and subsequent responsiveness for a
normally configured laptop.  You are correct that Photoshop CS takes a
long time to startup on windows, but for me Photoshop on windows takes
about the same amount of time to startup as Swriter on linux.  With
Photoshop, I know I'm running it (in windows) on a system that is way
underpowered for the task so I can't complain (but still need it). 
Word processing is something my laptop handles like a charm (i.e. no
problem under windows) so it is kind of depressing to see OpenOffice on
linux run at the same performance level as Photoshop does on Windows. 
As much as I love Ubuntu I wouldn't really feel comfortable
recommending it to my friends as long as this is the case.  

I did though last night make some of the OO performance
modifications (oooprelink, cache) and it seemed to help some.

With all that aside, I understood everything you posted about
ways to make performance improvements except for swapiness.  What
precisely is 'swapiness' and where is it set?
