Device Suitability- Laptop vs Desktop

Teacher- A laptop would probably be more suitable for a teacher because they would be able to take it home and continue after school, for example marking work.


A News Reporter- A laptop would be more suitable because it would need to be portable.


A Website Designer- A website designer may need more than one screen, however a desktop would be more suitable because it needs more powerful programming.


A doctor (GP in a surgery)- A GP would need a desktop because they don't move around very much and therefore they wouldn't need anything portable such as a Laptop.


A Traffic Warden- Although a Traffic Warden probably wouldn't need either, a laptop would be more suitable as it is portable.
