Choosing the right device

When recommending a device for a specific situation, consider the following factors:

 User Needs
o 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
o 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
o 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
o Higher-end devices often have more features but are also more
expensive. Consider the budget and whether the extra features are worth
the cost
