Linus Torvalds, Linux's creator, dislikes the GNOME desktop. There was a big flame war(s) between Linus Torvalds and the GNOME community. At one point he claimed that - "Gnome seems to be developed by interface Nazis and that its developers believe their users are idiots". And guess what? Who made the switch to Gnome?
Now, Linus thinks KDE 4 sucks and it is a disaster. From the computerworld interview:
I used to be a KDE user. I thought KDE 4.0 was such a disaster I switched to GNOME. I hate the fact that my right button doesn't do what I want it to do. But the whole "break everything" model is painful for users and they can choose to use something else.
I realise the reason for the 4.0 release, but I think they did it badly. They did so may changes it was a half-baked release. It may turn out to be the right decision in the end and I will re-try KDE, but I suspect I'm not the only person they lost.
I tried KDE4 for day or two.. and it had some nasty bugs and features. To be frank, KDE 3.5 was much better and superior to GNOME. Personally, I prefer GNOME's easy to follow clean interface without bugs. What do you think?
