I agree.  I have a lot of things turned off here but KDE4 doesn't seem
to be much if any worse than KDE3 on memory usage.  It seems to me that
KDE4 does a better job than KDE3 in a lot of areas.  Yea, I have 16Gbs
of ram here but I rarely go over 2Gbs and most of that is things not
KDE, like Seamonkey, Firefox etc.  I'm not counting cache. 

People seem to forget that Linux uses memory different.  It's also one
reason windoze can run with bad memory and Linux can't.  If the bad ram
is at the upper addresses, windoze may never use it but Linux will
unless a person reboots a lot.  I had to replace a stick of memory a
month or so ago in my brother's rig because of this.  I switched him to
Linux, Kubuntu I regret, and it got flakey.  I ran memtest on it and
sure enough, it was bad at the upper end.  He only has 768Mbs.  Maxed
out to I'm afraid. 

KDE4 using 2Gbs, I just don't see that happening.  KDE5 or KDE6 maybe
but doubtful.  That's a lot of memory.
