Some teams I've seen blindly follow the 'mobile first' strategy without thinking about what device their application is best suited for. Microsoft Word, Photoshop, and advanced developer IDEs are good examples of software that should be desktop centric. While there are text/image/code editors on mobile, the difference is that people end up crafting with these types of software. They put hours into them on one project and build something they consider truly great. Instagram makes sense on mobile because the amount of time you put into the app is likely under 10 minutes at a time. If you're expecting your users to craft, and to spend long periods of time building something in your app then give them a big screen and a physical keyboard; give them desktop/web. In addition, I think the point about not being able to rapidly fix issues is a pretty good one. Average app store approval time is now 7 days, and while its possible to do testing to prevent issues, I imagine most first-time startups are not going to be able to fully predict the impact of scale on their app.
