As listed, this only applies to outdated computers made between 2004-2007. Namely, Pentium 4's, Pentium D's, and perhaps some Core 2's from 4-7 years ago.
But as the article states: "A lot of these devices, given their age, will not be in good working order and does not support the latest versions of Microsoft products."
Most IT Departments in school systems have been switching to Windows 7 as a cost-cutting measure, not just because XP security updates expire in 2 years. The deployment tools on Server 2008 R2 for Win7 are insanely excellent. One can pull a central server to a distant school just once from a PXE boot, and it will peer-to-peer on the local network, rather than download a ~10GB file 30 times. Any additional drivers, software, and updates can be installed on the spot -- think Ninite, except before the installation. Doing things like installing XP from Ghost and babysitting the systems for an hour are obsolete, as is the staffing required for it.
But Windows 7 requires 1-2GB of RAM to run properly depending on software installed. With the crisis in the EU (PIIGS especially), it's very unlikely that they'll spend the money to buy DDR1/DDR2 to upgrade systems that don't. A 7-year old system is going to have hardware problems that low staffing can't troubleshoot, to the point where they won't even bother. And they certainly won't have the staffing required to take the time to set up an OSS system, much less train their staff on it, as it was only "recommended."
At best, someone might set up the ability to install Edubuntu through PXE boot, but they'll just be Edubuntu systems, nothing more. Some kids might play around on them at times, but otherwise, these old systems are just going to collect dust.
