I've been a long time Adobe user – by necessity rather than by loyalty to Adobe – and I feel it's great to have a new software publisher on the market to disrupt established ones. I'd be more than happy to jump ship, I love so far what Affinity has created (the naming of the latest addition aside).
I've been trying to figure out, what would it mean in practical terms if I ditched CC? I get a new client, easy, I can create from scratch, the learning curve is not too steep. So, what about all the existing clients and the countless ind. documents that I use as a template basis for the next report, brochure etc. update? These would have to be re-created from scratch in Publisher, a time-consuming and not very profitable solution.
Unless Affinity can provide rock-solid migration/conversion tools, I can't see myself jumping ship in the near future.
