It's pretty focused, I never upload camera photos to the cloud by default, that's crazy to me... so I want to be able to take a photo with my phone and send it to my desktop quite often, this does that, no problem.
Similar with copy and paste, being able to do that seamlessly between phone and desktop is pretty useful!
Never bothered with HandOff.
SMS is kind of annoying, I am used to being able to do that on my desktop, but probably going to switch back to Signal.
