Buying a PC using a loan or finance:
Pros:
- You get the PC now!
- You don't have to spend a lot of money at once.
Cons:
- You will pay more overall than if you had saved up.
Buying a PC using savings:
Pros:
- You will be able to avoid a better PC than you would have done if you had bought it on finance. What is a £1000 PC now will be £750 in a while. If you wait a while, you will be able to get that £1000 PC for £750, or you can use the £1000 on getting something even better.
Cons:
- You will have to be patient and save up.
