1. Nice to watch youtube videos on, which I do a lot. Both in portrait and landscape. I watch a lot of linus tech tips, photography videos, breadtube, and mandarin learning videos on it. I wouldn't buy it for this alone.

2. Really excellent emulation device. Powerful enough hardware and phenomenal screen. I use it as-is in portrait mode for the best possible DS emulation on-the-go. I can at least 4x the resolution in almost all games. I can also slap a gamesir controller thing on either side to turn it into a sort of switch-style emulation device. I play ps2, ds, 3ds, gba, gamecube, n64, snes, and nes games on it.

3. Good game streaming device. Mount the controllers on it and use moonlight or steam link to stream from my desktop PC, even if I'm not on local network. Or, use nvidia geforce now or whatever it's called. There's a separate link to servers here in Taiwan through taiwan dageda, so I get ridiculously good connection.

4. Pretty good note taking device with the stylus. This is the use case that drove me to purchase. I'm always experimenting with various ways of (handwritten) note taking, especially on books I read, and having all my notes right there on my phone is really, really nice. I never "forget my notebook" now. Well, unless I forget the stylus lol, or it falls out of my pocket, which has happened 3 times now, and the styluses are an absurd like 50$ or something, so, this device is not nearly ready for mainstream consumption. Similarly, it's great for banging out quick engineering diagrams or designs. I can export to image and throw directly on a ticketing system, or upload into slack. Nice flow, if I get a question from a junior when I'm on a train or whatever.

5. Reading books is very nice on it.

6. Using music-making apps, especially ones with piano rolls and keyboards, is phenomenal. I really wish it had an aux plug though. The jellyphone 2 has that and is the size of a pill bottle, and has dual sim and removable SD storage. No excuses. Although, my version of the galaxy fold 3 does have dual sim.

7. The width of the screen when folded is actually usable on my smaller hands. This was another big driver for getting it. Hilariously, my initial reason for looking for my next phone was, I was tired of big phones, and wanted one I could actually use one handed. Funnily enough the narrow width (that so many people complain about) of the galaxy zfold3 was a big selling point for me.

8. Using maps is really nice on it, and I'm doing this constantly because we're always exploring Taiwan.

In all, I don't think I'm down to drop another 1.8k (1.4 for me because I got it on contract) on a phone any time in the near future. When this phone bites the bullet (and the inner screen is already "tightening" and reducing the flatness of the unfolded state, so one of these days I'm sure I'll overextend and crack the thing) I'm going to get a nice small android something, I heard the Asus zenfone 9 is a good size at a fair price.

As cool as all the features are, it's not like I have all THAT much time to game or make music on my phone, and worse case, I can just toss the thing into my plane-toys bag when I have flights or whatever. The notes taking feature I still use occasionally, especially for diagrams, but I've since moved to a onyx boox e-ink tablet for that, mostly because this lets me hand-write annotate epubs, a feature I've wanted on a device for like, 15 years lol.

So, after ~1 year of using the galaxy zfold 3, I can say, it was worth the money ONLY because it fulfilled like 8 usecases for me. Take away even a couple of those and there's no way it's worth it. A better alternative would be a jellyphone or pixel + a small affordable android tablet in the bag with a stylus. Spend the remaining on a previous version op1 or opz if you're really into music making, or a steam deck if you're really into gaming. Or shit both lmao, you're right that 1.8k is an insane amount of money.

Edit: looking through the marketing material, I'm not seeing any stylus usage on the pixel version. Even if a stylus would technically work, if the responsiveness and sensitivity doesn't allow for note taking, this thing doesn't make any sense to me. On the samsung foldables, the responsiveness of note taking with the stylus beat out literally every other device I've ever tried it with. It is phenomenal.
