Workers keep the laptop for long documents and the phone for calls, chat and authentication, switching between them dozens of times an hour without standing up from the desk.
Stands, short charging cables and low-profile keyboards are now sold as a single bundle, because a phone lying flat on the laptop palm rest blocks the trackpad.
The practical upgrade is not a faster chip but a better pairing setup: quick handoff, a shared clipboard and one charger that tops both devices from the same outlet.
