Open source software on Windows? You bet.

A few weeks ago I blogged about Microsoft's new if-you-can't beat-them-join-them attitude towards open source software. But have you noticed how much open source software already runs on Windows?

Sure, everyone knows about Firefox, now used on nearly one-fifth of all corporate (mainly Windows) desktops, but there's so much more on offer than just Firefox these days. Surf over to Open Source Windows, and you'll see what I mean. Here are a few categories you'll find: Instant Messaging, Email, Word Processing, Spreadsheets, Sound Recording, FTP, IRC, Security, and even Accounting. It's a whole new world out there for Windows desktop users – and I haven't even mentioned open source SaaS.
