I could no longer resist, in spite my notorious lack of spare time... It began with installing SUSE 11 via KDE4 Live CD on my eeePC. On my desktop PC I had been trying KDE4 since the RC's where released with a special user and was quite happy I could come back to 3.5 for daily use. I was really astonished how very well even 4.0.4 was looking and behaving on the eee 701.
Since the release of kde4.1 RC1 I switched my default also for the desktop mashine from 3.5.9 to 4.1 and am very fond of it. All that did commit to KDE4 did and still do a great job.
