The Affinity applications get a lot of things right, and do some things better than Adobe already. And obviously the pricing and permanent sale model are much more attractive than Adobe's subscription model.
They do also have some almost unbelievable limitations, where what you'd expect to be entry-level functionality simply doesn't exist, and they lack any sort of plug-in ecosystem and all the extensibility and customisation that brings.
But saying that, it's not as if Adobe's applications haven't had bizarre omissions over the years, and they've had much longer to fix them. Hopefully Serif can keep up the momentum and community good will it's built for the Affinity suite and in time they'll close the gaps.
Are there any specific examples that come to mind? I recently heard about Afinity and am planning to give it a try next time I need a Photoshop or Illustrator replacement.
But then again, for a very long time very basic search and replace options were missing in InDesign, so as I said before, it's not as if Adobe's software hasn't had its share of bizarre limitations over the years as well.
