So, you are used to patchwork apps, Mr. Nyhus, right? I rephrase your question the other way round: Why should the users who are preferring RAW converter and DAM in one app, use multiple apps which tend to work worse in terms of collaboration? Have different update periods, sometimes not working with certain RAWs, some other times not working well with the RAW converter, usually not showing the edits, therefore you always need to export JPGs, some apps making a mess in the XML sidecar. Coming from Aperture, I have a serious allergy against all those wannabe DAMs and prefer much an integrated workflow. As far as I know ( and that is not very far), none of the apps you listed is able to show edits directly in the RAW file. And that makes the whole process very slow and uneasy to handle.
My guess is, you never worked with Aperture? You are used to copy RAWs into other folders, instead of dealing with crossreferenced files? You like to add keywords so you have a least a bit of a chance to find images?
I think, we can calmly remain confident that Nik Bhatt is able to manage his roadmap and work according his priorities. And btw. not the developer produces JPGs, but we as Nitro users. Aperture left a big gap in the DAM world, bigger than Non-Aperture users ever could imagine as they are used to their workflow. There are plenty of RAW converters, but very few with a halfway working DAM and none being able to do what Aperture could do. Some of us still miss this great app. And your DAM needs might differ from the needs of others.
