You haven't installed Windows in a decade.
Some devices that worked out of the box on Linux but required drivers on windows, just off the top of my head: Bluetooth USB dongle. USB wifi module. Logitech webcam. Focusrite audio interface. HP printer (actually this one required firmware on Linux too, so that's a draw). XBox 360 controller (required a driver on Windows 8.1. Maybe that's changed in the last few months with windows 10).
I admittedly don't use Bluetooth and every time I've tried it's been a horrible experience.

Mine works fine, no driver download.

I don't have one.

I haven't used a printer in probably 10 years.

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.
The wifi modules were a generic device with a Ralink/Mediatek chipset, and another TP-Link branded device. I don't recall the specific webcam verson, it's an older Quick series one that really should have worked.

In general this is a situation where Linux shines, because hardware tends to remain supported much longer as long as there's someone willing to keep the driver compiling. With TWAIN scanners it's a lot easier of course.
