Traveling salesmen are most likely to use laptops and tablets .

* Laptops: Offer a good balance of portability, processing power, and screen size for managing schedules, routes, customer information, and potentially accessing CRM or route optimization software.

* Tablets: Provide even greater portability and are convenient for quick data entry, map viewing (using GPS and mapping apps), and communication with clients. However, they may lack the processing power of a laptop for more complex tasks.

Smartphones are also used for communication and basic tasks, but laptops and tablets are more practical for the bulk of a travelling salesman's work. Desktops are far too unwieldy for travel.
