Laptops also take up less space, and can look neater than a desktop PC. A laptop may generally be more personal, especially as you can carry it around with you anytime. Desktop PC's seem more suited to family use.

Laptop PC's also have an inbuilt mouse, though you can still choose to use a external mouse if you prefer. Laptop keyboards tend to be more compact and not as bulky as desktop PC keyboards.
