KDE - KDE SC 4.4.0 Caikaku Release Announcement
If you want to try it. Go install kubuntu(my choice) or ubuntu first and add the KDE repositories.. more details from the web..
So i'm using it right now typing this. it runs great, it's very usable, i was showing it off to my friends and yeah nasuya sila hehe, of course with eye candies turned on, a turned on always :P
installed on Kubuntu 9.10 64-bit - wubi installed on Dell XPS M1210
improvement i noticed over the KDE 4.3 of Kubuntu 9.10
- Kickoff app now auto recovers from a crash.. just like windows xp
- new theme
- Desktop Activity settings
IMO,the best linux desktop out there.. now it just got better...
