Microsoft's Biggest 'Threat'
Microsoft periodically shuffles around what it thinks to be its biggest 'threat'. Right now, it's apparently open source. Yesterday, it was Google.
I disagree. Microsoft's biggest threat is itself. Particularly the higher-ups (here's looking at you, Steve...) for their refusal to embrace the open source community, rather than spouting FUD and lies.
I would not be using Windows at all if there weren't so much OSS that ran on it. I'm sure that a lot of people think the same way. The fact that Firefox, Thunderbird, and many high-profile programs have Windows ports makes it seem like a Windows computer is a viable workstation. Having those programs available is a reassurance that I'll have the same programs available no matter where I go.
