Blake, you're right that the vast majority of PNW _vendors_ (i.e. technology service providers) are MS shops. That's because almost all (at least 95%) of the vendor ecosystem here is supporting Microsoft or clients Microsoft directly connects vendors with. (We're primarily a non-Microsoft vendor - we'll do MS-based development if required, but we don't choose it for new projects, and 95%+ of our work is on Linux - but we are one of a very few exceptions at any scale.)

As noted by others, _startups_ - being created from scratch by people choosing their tools - absolutely use a wide variety of platforms. I expect that the numbers would bear out a higher percentage of Microsoft-based startups than in other locations (and there are a number of successful startups in the Seattle area with Microsoft-based platforms), but it's certainly not a significant majority.
