Not sure about the flip phone shown in image but my Fold4 was bought in attempt to replace my laptop which I have to lug around with me constantly due to work. So far it's able to do around 85% of my work, which is good enough. Definitely not a phone for everyone, but for what I use it, it does the job pretty well. There are downsides of course, but benefits as well. Bigger screen does come handy but not as often, unless used as laptop with bluetooth keyboard and similar. I have used it on few occasions as sketchpad, because I have a pen and a huge screen.
