As with all things, YMMV. I've had my OP-1 for nearly 10 years and I've gotten a hell of a lot of use out of it. As a super portable, battery powered instrument with lots of different synth engines and diverse FX it's been great for travel, noodling on the couch, and jamming with friends.
I also have to give TE props for their long term support and updates on the OP-1. I mean, just last fall they added USB audio in/out on a 10+ year old synth! Few other major synth manufacturer I know of hav as good a track record (Novation is actually pretty good in this respect as is Elektron, but for the most part they're fixing bugs not adding new features).
Compare this to another boutique synth outfit like DSI/Sequential -- my DSI Pro2 purchased in 2014 only got about 4 years of support before they dropped it like a hot potato. Tempest suffered a similar fate. Never buying another DSI/Sequential instrument again...
