15 years ago people could not believe I used Mac as a development machine.

Are you sure it wasn't more than 15 years ago? Because the way I recall it, after 10.2 was released most devs seemed to concede that Macs could at the very least serve as a passable way of getting Unix on a laptop, and once Xserve RAID came out even some greybreads where at least considering the idea of putting Apple hardware in their server room (even though very few eventually did).

Positive. This is in the UK. At that stage even younger less corporate developers couldn’t understand it at all.

counter-point: I started seeing more and more developers carrying (personal) Macs in London in 2005 in pubs and at events and by 2007 99% of those I knew were using a Mac.

By 2007 many had a Mac laptop provided by their empoyers (myself included).

Of course, agree it wasn't the absolute majority (it;'s not the absolute majority today either) but far from rare depending on your circles
