I am just a little bewildered why Slashdot thinks that four users is anything to get excited about:
The fact that one computer science laboratory can support up to 60 users with only 15 PCs is really attractive for low-resource groups and countries.
Many, many folks ran 30-40 users on 80386 Xenix machines! Ok, yeah, those were dumb terminals. So? Use LTSP and run dozens of users off one box. I have no idea how many you could run, but I doubt even 100 is at all impossible.
Yes, each of those machines is a full CPU (or an X-Terminal), but they can be weak, inexpensive, even "junker" machines, because all they need to do is drive a display. And if the app is character based, you don't even need that much power!

Specific links that take you to pages that allow you to purchase the item I reviewed are very likely to pay me a commission.

Well who knows what Slashdot thinks :-) But the important bit about this story is that they've managed to get multiple consoles hanging off a single machine. Four monitors plus four keyboards plus four mice equals four console sessions. No X-terminals and no network gear required. That's kind of neat.

It is neat, but the supposed benefit to poor countries etc. is, I think, dead wrong. As I said, an LTSP setup could handle dozens and dozens of cheap, otherwise near useless machines.

Well, I think that many places don't have mounds of old PC's laying around like we do in the US. Especially if they are only recently getting into computers.

Not the same idea (doesn't save any money), but related and interesting:

Userful has taken a more comprehensive approach to multi-user linux systems than the HP441 and they've been doing it for years. You can plug up to 10 monitors into a Userful computer, and their software installs on top of any linux Distro (i.e. Fedora 2, Mandrake 10 etc.), and works with a whole slew of video cards. They also sell pre-built systems similar to the 441, they seem to sell a lot to libraries in particular. http://www.userful.com
