I think for most homes, an MFP is a nice-to-have. I have one and I never use the scanner, the vast majority of times, it’s sufficient to “scan” with my phone to send as a PDF. My next printer will probably be a color laser printer-only.

For SOHO, SMB, and enterprise, though, I think it comes down to square footage. Especially when you start getting into the bigger ones. Turns out that a copying machine does a lot of the same things a printer and a scanner do. A separate, discrete copying machine doesn’t make sense in a lot of places, and I’d imagine it’s very cost-effective to get a big MFP instead of three discrete devices. Especially when you’re dealing with leased equipment.
