I'm just about done with our thin client updated operating system, and am *very* impressed with the HP 4410t laptop form factor. It boots super quickly to the chooser, and the Intel Xorg drivers found in Debian Squeeze/Sid are excellent. 3D rendering is fast and responsive, video playback is fast and frame rates are high. I finally got Pulse installed and it found the audio hardware and playback is excellent.
My thanks for everyone that works on all of these software packages, you make my job a lot easier!
Shot below is two concurrent video and audio streams with cube turning. The 4410 was able to do this perfectly with no dropouts. This test was performed on the 1Gb ethernet port and everything is being pushed over the network.
