$1400, no way I'm purchasing it then. I would have expected half that.
I suppose it's all about frames of reference and the four things I'd compare a surface duo to are laptops, the galaxy fold, a regular smartphone, and a regular dual screen phone. The Duo wins in two of those comparisons outright by being cheaper than the fold and more productive than a regular smartphone but compared to a laptop like a Samsung Galaxy Book S it's worse for productivity. Compared to an LG smartphone with the Dual Screen addon (LG V60, Velvet, G8X etc.) which come in about half the price while having similar or better core specs it's absolutely not worthwhile. The only things the duo has going for it over LG + Dual Screen are a smaller gap between screens, a more elegant execution, and better software support which while worth a couple of hundred bucks perhaps isn't worth doubling the price! It even loses features like cameras and wireless charging, NFC, in-screen fingerprint readers.
