In my experience browser based apps are sooooo slow compared to native ones. Also no offline support at all. And they have access to all of my data because I have to upload it. I just want to use lightroom to edit my vacation photos, I don't want to upload all of my photos over my slow internet connection just to edit them in a high-latency browser app. Also I'm likely traveling in a vehicle without stable internet.
