What advantages/disadvantages do desktop computers have?
Most powerful form of computing. In order to access the most power in a computing sense you have to use a desktop. The most powerful laptops and tablets don’t come close to competing.
Modifiable. The amount of customization you can perform to your desktop PC is unlimited. If you ever have a task that requires a large amount of power or resources than you have to deal with a desktop PC
Immobile. Wherever your desktop PC is kept is where it stays. You can obviously move it wherever you want but not like a laptop which can be used anywhere within seconds.
Cheap. Pound for pound in processing power and all else your desktop PC is much, much cheaper than any laptop.
Large. Even modern desktop PCs are large and take up room. If you have limited space or a small desk maybe a desktop PC isn’t for you.
