Here is my story, I created my first video in 2011 after taking a trip to Maui with my family. I was editing on a cheap HP laptop and Adobe premier elements, the video sucked but I saw the potential (

https://youtu.be/IC8s4WeknUs. I then moved to MacBook Air and Adobe Premier Elements which sped things up and was fine for 1080 video, my editing was getting faster also.
Then in 2017 I moved to 4k and although my 2013 MacBook Air was still working, I had some pretty serious limitations I had to workaround. I would film in 4K and edit the timeline in iMovie because it was optimized for MacOS and cut 4k video with no issues. However, colour grading was pretty much non-existent unless you wanted overbaked filters applied. I would export the video as ProRes in order to get around the 40mbps max bit rate of iMovie and import that into the free version of Davinci Reslove for colour grading. Resolve could handle the Prores file mostly OK (some choppiness) and I could split the video and apply colour grading, horizon leveling and export the final video as about 75mbps (anything higher would overheat my MacBook and crash), the export would take about 45 minutes for a 5 minute video.
I picked up an iPad Pro 11" shortly after it was released and right after discovering LumaFusion existed, I was surprised that it could do everything I needed it to do but extremely surprised at how fast it could export 150mbps videos - almost real time! I was able to import all my LUT's that I was using in Davinci Resolve. I do a lot of scuba diving videos as well which require some pretty strong colour grading, LumaFusion could not handle this to my satisfaction. But no problem, I performed my usual grade in Resolve and export the LUT to LF which gives a great starting point which I can tweak in LumaFusion.
Over the years I've cut down the time it takes to create a video from 40 hours to about 4 hours, it's much easier sitting in front of my iPad doing this compared to a laptop. With iPadOS 13 on the horizon (I'm running the beta now) this will complete the solution for me. I no longer need a laptop.
I've cut down the amount of equipment I carry now too, just an iPhone + gimbal and my iPad (for the most part), throw in a compact superzoom for wildlife trips. Now I just need to figure out how to cut down my 9 pound rig for underwater video, but that's a different story.
Here are my latest videos done in LumaFusion, nothing too fancy but great for memories:
