I just had to write it somewhere eventually, but while we were at the RDS, I had no problem using our 433MHz 128M machine with Kanotix (05-02) installed to run KDE 3.4, Firefox, OpenOffice.org 1.1.X and OpenOffice.org 1.99.X simultaneously! The OpenOffice.org was taken from klik while the others are part of the normal installed system. Performance was not inspiring, but anyone who would actually try and run such bleeding edge software on such a limited spec machine would surely not have expected any more? Certainly it proved to me just how useful klik could be as we could fire up ooo2 without having to risk breaking a display machine.
For anyone curious, the other machines on the stand were, afair, a PIII 700 w/256M and an amd64 2GHz w/1GB plus some laptops I could tell you nothing about and the Sparc monster which I think would make an interesting coffee table
