That's because I'm thinking no one in their right mind really likes Adobe, and I think no one can honestly say they actually enjoy using Photoshop, but rather up to this point they had no other options. […]
A million times this. I was about to say the exact same thing…
But I should add that the few, true fanboys are probably sitting quiet on the sidelines for fear of sounding ridiculous. As far as the creative market is concerned, amateur hour is definitely over and the competition will heat up, quickly. The nice people from Serif stopped short of formally promising a DAM which could legitimately claim the title of Aperture's successor and, considering their engine was mostly coded in C (please correct me if I'm wrong), it
is conceivable that, if their prospects are good, we may one day see a cross-platform version of Affinity (at version 2, 3, 4? Who knows which and, really, who cares? As long as it comes to pass…).
And that, my friends, would mean “game over” for Adobe (or for the CC subscription model, at least). That's also another reason why the fanboys are not very vocal right now… On one hand, more licensing options on the Adobe camp would serve their interests; on the other hand, another strong player in the market could conceivable make the tables turn or, at the very least, force many of them to buy a second package in order to be able to open an influx of .af* files sent by their colleagues.

Oh, I also forgot to add that one of the reasons Affinity's performance on OS X x64 is so great is the fact that its development was originally geared to
iOS and A-class processors… So we may end up seeing some very cool companion iOS apps from Serif as well.
I believe the fanboys are taking a wait-and-see approach, and though that may be smarter than badmouthing a serious contender, it's definitely not as smart as taking advantage of Serif's special offers (which make them even more of a no-brainer… Case in point: with Affinity, I will end up spending just €120 on a [almost] fully featured and fully, perpetually licensed suite, instead of the €300 I plunked down for CS5 Design Standard
for Education back in the day!!) and skating to where the puck may very well end up being.

Interestingly, many here are taking the latter approach, which is extremely commendable. You all make me proud of belonging to the MR community, really.
By the way, hi Andy! JGD here!
