"XP still dominates here in Ed Tech. Sure, we have lots of Macs and Linux has made some inroads in our market, but we all know where the lion's share of the market sits. And in some ways, why not? XP is easy, there is a huge install base, it keeps most of our users happy with no training (assuming we can keep the malware at bay), all of our software runs on it, and it's been around long enough that most of our students can support it, let alone IT staff.
"How many people actually use free XP support from Microsoft? Maybe for Windows Server or SQL Server, but plain, vanilla XP? Whether Home or Professional, we all know how to support Windows on the desktop. Even the least competent techs can find their way around all of the basics that we'd need in most educational settings? Can you get it online? Can it print? Can you install software?"
