Outside of software, the only ones I remember that I cared about hardware-wise was USB Display-out & a Stylus. Though some android tablets are getting tiny fans so I do like that, and two USB-C ports does make up mildly for removing the audio port

For what its worth, some Samsung phones can stop charging while the plug is in, while also not disconnecting anything on a USB dock (such as internet)

Last time I checked, there were no kills in 2fort because everyone was taunting

I had it work once for a wifi issue that was caused by an update, during either Vista or Win7 era. Outside of that, it fixed an audio problem for Win10 on a single app.
