Comparing thin client solutions

Hello people I am beginning evaluating thin client solutions and the
most promising so far seem to be PXES and LTSP.

I hope I can find someone here to help me understand the differences
between PXES and LTSP, and in what circumstances should one pick one
or the other. I understand that PXES doesn't use NFS share, is that
all? How dows this affect performance compared to LTSP? What are the
other differences?

Also, could someone tell me some thin client models or vendors
compatible with PXES?

Thanks in advance,

Matheus
