I admittedly don't use Bluetooth and every time I've tried it's been a horrible experience.

Mine works fine, no driver download.

Mine works fine, no driver download.

I don't have one.
> HP printer (actually this one required firmware on Linux too, so that's a draw).
I haven't used a printer in probably 10 years.
> XBox 360 controller (required a driver on Windows 8.1. Maybe that's changed in the last few months with windows 10).
Nope. Not on 8.1. Not on 10. There may be an optional driver for it (may be-- I've never seen it), but it's certainly not required. This one I can firmly say you're wrong about. (Unless you have like a Chinese knock-off Xbox 360 controller-- the brand-name ones work.)
I had a great experience the other day when I plugged in my ancient CanoScan LiDE 200 scanner I bought back in the Windows 2000 days, and it worked flawlessly in Windows 10, no drivers or software needed.
