Just surfing the internet, watching movies… What does not break so fast?
PC lasts longer.
For surfing / watching movies you do not need to worry that there are heat problems on the laptop. But laptops can always fall down, and in case of a defect can't be exchanged individual parts but the whole device is in the but.
But I would buy a tablet for surfing / watching movies.
In order to pour what in a PC you have to make a real effort - the laptop is enough to knock over a glass.
It is also difficult that you a PC falls down - the laptop no problem.
etc.
In addition, PCs are more efficient at the same price.
I think the pc will live longer. Alone on the basis of the fact that a laptop is usually a mobile device, and the hard drive in this way just more shocks, etc. Delivered.
And expandable until there are no more "fitting" parts.
