256 megs ddr = 80 euro. Reason my box has 256 meg :) I'll upgrade once I have
a game that needs more for textures.

I use kmail for 5000 mail-maildirs ;)

OOo is also ridiculous. It should share nore with the other available open
source software - such as widgets. I'd be delighted to save my files with
those gorgeous QT dialogs instead of the pathetic built-in windows ui clone
they use now. I wonder why Sun hasn't used Motif for the Staroffice UI
actually.

KGhostview is still buggy. The first pdf my dad tried to open with it showed
up sideways, off course the rest of the page in place. Grmbl...

... and virtual memory under Linux is "pretty good". It's monitoring it that
sucks ;)

Actually I'd appreciate if someone took parts of kdebase and libs under the
magnifier glass again :) .
But anywa, they're going in the right direction. Performance has had a lot of
attention between 2.2.2 and 3.0, and kde becomes more modular each release.
