I have a wireless scanner and printer combo (HP 2450). To set this up on windows, I turned it on, pressed the WiFi button and the WPS button on my router and File -> Print and/or open up Fax and Scan and that's it. Just works. No setup for scanning or printing. On linux, 30 minutes arguing with hplip and the output looks like ass whatever switch you flip and SANE doesn't even see it.
Then there's PM. On my 9-cell Lenovo X201, 8.5 hours on windows 8.1. I managed to nab max 5 hours out of every Linux distro I tried (Ubuntu, Debian, CentOS) with powertop tuning. The cruel irony is that CentOS gets better battery life in a VM in Windows than it does on the bare metal.
YMMV as they say but I really can't be arsed with anything that gets in the way of doing stuff these days. Tuning a Linux distro was fun about 10 years ago for me. Not any more.
