Okay, so I took the plunge and installed KDE 4.1 on my own system.
I figured I came with KDE since KDE 2 so why not stick this one out, can't be worse than the earlier pre KDE 3 versions...
So far it has been mixed feelings brewing in my chest. The guys porting software are not doing a great job, mostly the 3rd party software for KDE is lacking HUGELY from qt4 support which means it is not a clean transition.
You still need qt3, you still need kdelibs-3.5.9, you still need some arb lib that kde 3 uses...
I uninstalled KDE 3 completely (well as completely as some apps are allowing me), so I do think that we have to give some people on the 3rd party bandwagon a bit of stick as well and not just look at the KDE devs for all the shortcomings of KDE 4.
I can live with the odd traces of KDE3 software still on my system, but it would have been so much better if one were able to make a clean transition. And it is not like the devs have not had enough time, KDE 4 (svn) has been around now for almost a year.
Lets see, I'm determined to stick this out, might just switch to the svn repository, but I have a feeling that will break more stuff than fix small annoyances.
