Hi Toya,

We've been using LTSP for over one year now. We've had our Ubuntu-based 
Linux lab for three years now. In fact, now that I think of it, we have 
had Linux machines in our labs for a while now. Before we had Ubuntu 
machines, we had RedHat, SuSE and even Lycoris at one point 
(http://en.wikipedia.org/wiki/Lycoris_(company))! Anyway, the 
significant problem with individual installs was in keeping the machines 
maintained. That's why we switched to LTSP with Edubuntu.

That worked great, but some budget somewhere yielded to a complete lab 
upgrade, which resulted in core duos on each desktop (thank you, 
taxpayers!). while LTSP worked well in the thin client setup, having 
core duos with 2GB RAM sitting there doing the work of a PII with 64MB 
RAM was somehow not justifiable. How do we leverage the power of each of 
the 32 workstations? That's where the lowfat client came in. 
(https://help.ubuntu.com/community/UbuntuLTSP/LTSPFatClients)

It works a lot better because the lowfat configuration allows for 
crunching on each workstation locally, while loading the server with 
networking, dhcp, nfs, ldap and backups etc. Latency-sensitive apps 
perform much better. USB media plugged into the workstation also behaves 
well because now it is actually working locally. Updating the image is a 
bit more work, but not that much of a hassle.
