I have been using LR since ver. 1, and I own LR 5.0 now. I purchased every release...until Adobe went to a subscription only basis. Since that news, I've purchased everything Serif has produced for the Mac. (Many, many years ago, when I used a Windows PC, I became familiar with Serif).
Adobe has lost all of my business (I also own Adobe Design Premium 5.5), as has AutoDesk, which followed Adobe's lead. Due to this, I was very happy to hear about Serif's Affinity software, which I became aware of after I started looking for replacements.
The DAM news is especially good to hear. I'm very comfortable with the way LR evolved, and I hope Affinity's DAM will be just as user friendly, because I'm looking for a long term replacement. That said, I would like it to be an easy transition, i.e., I don't want to loose all the work I've put into my files in LR. I just don't know how they will be able to bridge our libraries from LR into Affinities...if they go with the same kind of arrangement.
In the mean time, I'll keep using what I have purchased from Adobe and Autodesk, until I get more familiar with Affinity.
