Feedback from a potential customer: I despise 2-device limits. I used DEVONthink for a decade but dropped it because of that exact thing.

At home, I have a Mac Studio[0] set up in my office with my music stuff, and I'm writing this on my MacBoor Air[1] here on my lap in the living room. I also have a work laptop, although it's safely tucked away in my backback right now. My wife has an MBA, too, but that's hers and I don't mess with it. So I'm elbow-deep in Macs that are used solely by me, and I bounce between them regularly.

The 2-device limit is a dealbreaker for me. It's where I stop reading. I don't care if it cures cancer: I won't buy an app that makes me pick and choose which of the devices in my care I can use it on. I'm sympathetic to why vendors pick that limit. I get that you don't want me to buy a single license and spread it around my friends and work circles. That's completely reasonable and understandable. And yet, it completely breaks my use case. I bet I'm far from alone in this.

[0]A previous job let me keep it when I left.

[1]I bought to hack on personal projects instead of using [0], which was work-owned at the time.
