It's even a very small and biased subset of the total developers in the United States. The majority (I would say vast majority) do not attend conferences. Sometimes because their workplace won't fund it, but often simply because they find no value in it. I personally gave up going to conferences years ago partly because workplaces treated it almost like they were giving me a vacation that I should feel grateful for, but it certainly didn't feel like a vacation. And afterwards I would try to itemize the value I received...to have nothing (talking to developers of the vendors face to face was, if anything, less productive than simply dropping a note on a discussion board).

So that subset often comes from more moneyed employers, or are the "see and be seen" sort, or they really get value out of it. For the former two sets a Mac is a pretty likely device.

I'm heading to a regional one in August that is registered as a nonprofit and is less than a week's salary to attend (and I work in the public sector in the Midwest so don't think that this is big left cost salary).

That said, even with a strong Microsoft bend to many session technologies, macs still are several times more frequent than non-mac.

Since the conference isn't trying to pull in big bucks (its a break even - 501.C non profit even), attendee costs for 2017 are $425 (food included - and they don't skimp on food). Even if you're going to add on the hotel the conference is located in, its only $175. Toss in a plane ticket and it is probably still less expensive than the national ones for the "get in the door" ticket.

There are lots of regional or local conferences that are not absurd in pricing.

For another example of an upcoming local one: https://stirtrek.com which is a one day $99 one. Its draw is likewise local.

Yea, NoFluff is $1000 to walk in the door for two days. I'm very glad that there are others that are closer in line with not needing to drain the training budget to go to.
