The one pain point for me is film and book scanning. AFAICT there are exactly zero Linux software packages that will play nice with my Epson V800 or my Fujitsu SV600. I keep a Windows laptop around (second-gen ThinkPad X1 since you asked) and its only job is to talk to those devices. Firewall doesn't let it get on the internet, its only network access is to move scans onto my NAS.
