So, yeah, I kinda hate Apple (I like my stuff configurable), but I wonder more and more how long is it until I drop other devices/OS', and buy an iPhone + MacBook.
Nah. It's any Linux computer [0] <-> Android [1].
[0] KDE Connect works on Gnome as well.
[1] It can connect to any Android device as it has an Android app.
And as other's have commented, it has many more features than just the clipboard.
I'm using an iphone now and the biggest thing I miss from Android is KDE Connect which is not available on iOS.
You can copy phone numbers, quotes, etc., I just never do. Given you can cloud store all of it, why bother with manual local sync.
In short it seems cool, just doesn't fit any workflow I use so I was curious what THEIR use case was.
