After several people said KDE 4 is sutible for low end hardware and works just fine on it I had to give it a try on my laptop which I use when I travel. It is a second hand Sony Vayo PCG-Z600LEK, about 6 years old, super slow and I called it gna since it is giving me headaches repeatedly. Working on it with KDE 3 is doable but not a nice trip to the Caribbean if you know what I mean
Today I installed RC2 on it and damn I am impressed. It is so much faster. Everything works just snappy. Windows switching happens instantly. And so on…
I already loved KDE (and KDE 4 especially because of all the awesome new stuff) but this is fantastic.
Thank you everyone who put work into it. We rock!
