Oh, Microsoft... I think my Duo 2 (upgraded from the Duo 1, that I handed down to a family member) is by far my favorite phone I've ever owned. It's nearly perfect for me, except for the missing Qi charging, which I originally had been expecting would be added for the Duo 3.
Yeah, I'd prefer a foldable screen over dual screens, IF it could also fold 360 degrees, but given a choice between 1 screen that only folds 180 degrees, or 2 with a gap but that fold 360 degrees for tent mode, eliminating the need for that absurd external display, and other features, I'll take the dual screens every day.
I also love the 3:2 aspect ratio of each of the Duo screens. I came from a Samsung Galaxy. I find it's 18:9 aspect ratio to be terrible. When I use those now, I feel like I'm working on one of the sides of an old #2 pencil. They're so narrow and cramped as to be useless (for me, I know many people love that aspect ratio).
But yeah, hard to trust MS with any mobile hardware now. I had originally said (wrongly) that because the Duo came from the Surface team, it would get proper love for an extended period. Nope.
MS just seems perfectly content to give its most loyal customers the finger. As a former (and partially still) product development manager, I understand the need to cut losses and drop a failing product, but MS' approach to the Duo and the way it treats it post-launch is the CAUSE of the problems, not the other way around. If you treat your product releases as mistakes and don't bolster the customers who buy them, the product will fail. This is one of the main reasons you see ads on TV for products: it's not just to sell new stuff, it's also to make existing owners believe they made a smart choice so they develop brand loyalty. Marketing 101 (OK, maybe 201), but apparently totally alien to MS.
We have 5 Surface devices in our house: Surface Go, Pro, Laptop Studio, and Duo 1 and Duo 2 (not to mention 3 Xboxes along with other Windows systems from HP and Fujitsu and multiple custom-built Windows desktops). And I had Windows Phone Lumias before that. I don't know that MS can win back my trust on a phone. Maybe they don't want to. Maybe this indicates they're officially out of the phone business for the foreseeable future.
If Linux and Apple software and Mac OS weren't so unusable for productivity work, this would make me want to switch ecosystems. At a minimum, I'm more likely to go with another HP Spectro over a sixth Surface for my next laptop.
Just sad and a bit disgusted by the whole thing. But for now, I'm going to keep using my Duo 2 because for me, there's nothing else out there anywhere near as good.
