Hi,

there is currently a poll on www.linux.com about amount of available memory.

http://www.linux.com/polls/index.phtml

I conclude from this that KDE-2.0 will be usable on 98,4% of these machines 
and run very well on 84%.

The number of total votes is beyond 10000 so it is statistically not that bad 
but mainly tells something about linux.com readers than linux users...

Regards,
