This is not quite true in PCLinuxOS. You can have any number of desktop 
environments installed at the same time to choose from at login -- with the 
exception of KDE3 and KDE4. There it's either one or the other -- unless you 
are willing to do quite a lot of tweaking.

On the other hand upgrading to KDE4 is fast and easy if you follow the 
instructions on the PCLOS forum. Waiting a couple of days might be a good idea 
though: PCLinuxOS 2010 is expected very soon.
