I mean, I'll put it this way
In my eyes. Laptops are useful when you have work on the go.
Desktops however is like working from home - because you can do what ever the hell you want, and make it better any time
while laptops are very limited to what you can do.
It's like this
laptop = A Lego Toy where all the pieces are glued together and you can't do shit about it.
Desktop = A Lego toy where you can take things apart and addon to it
"heathen! Burn the heathen!"
they both have their uses
