That's interesting...it shouldn't make a doggone bit of difference
whether you're running on a P4 thin client or an iMac thin client. 
Actually, the Power Mac client I was thinking of when I wrote the above
was my orange iMac sitting in my living room!  It's just about as fast
as any other client I have.  One of those other thin clients is a Sun
Ultra 5 (270MHz CPU), and it, too, is a good performer because of its
Fast Ethernet NIC.

The most critical thing you need on the thin client for good general
performance (e. g. OpenOffice.org and Firefox, not fancy 3-D graphics
stuff like Compiz/Beryl) is a 100Mbps Full Duplex network connection. 
The server should of course have at least 1Gbps FDX.  The built-in
video, ATI 3D Rage Pro, will do nicely for that.  Full-screen 320x240
video will drop a few frames, yes...but it does work.  640x480 hi-res
videos, that might be painful....

If you want to do that, then I would suggest Jim McQuillan's thin
clients at http://www.disklessworkstations.com.
