savings on office space too, if you have 20 staff in an office and most are working 2 or 3 days a week from home, you can rotate it so you only need 8 or 10 hot desks and a smaller location, so cheaper rent.
Most staff can work using a laptop, so all you need in the office is docking stations, unfortunately for me, my software is one of the few that still runs better on a slightly higher spec desktop or an expensive top of the range gaming type laptop.
a lot of our designers have the standard laptop now, as I know because the requests I get to convert files and do all the processes that CAD really only does well on a desktop are on the rise, if I were moved to a laptop (as they want me to if I return into the office), then we would have nobody to do those specific CAD processes usually involving larger files (40+ Mb)
