Choosing the right device
When recommending a device for a specific situation, consider the following factors:
User Needs
What tasks will the user be performing? A graphic designer might need a graphics tablet, while a data entry clerk might need a keyboard with a number pad
User Skills
Is the user comfortable with the device? A touch screen might be more intuitive for some users, while others might prefer a mouse and keyboard
Environment
Where will the device be used? A wireless mouse might be suitable for a clutter-free office, while a wired mouse might be better for a public computer lab to prevent theft
Cost
Higher-end devices often have more features but are also more expensive. Consider the budget and whether the extra features are worth the cost
