This is a most excellent place for technology news and articles.
So I can keep it in a central location since there's no ~~food~~ place for it in the office, and print being able to quickly print something from my phone is convenient (like a 4x6 photo from my phone to give to a visiting family member on the spot).
FWIW you can always disable wifi if you don't need it.
Gotta have a food place for the printer.
100% essential.
