I think the majority of users want their data in the cloud. Edit on desktop, send link to work to client, client looks at it on their phone. No need to export. Change something, client sees it immediately.

Even if it's not business. Sister shares video she edited of party. Mom points something out, sister makes edit.

I'm not saying there's no use to local only solutions. I'm only saying that I suspect for most users, the benefits of in the cloud are something they want.
