What you are bound to get in a school computer:
Bad Antivirus software
Extremely strict parental controls
The inability to download anything
An old integrated graphics card
The desire to buy a more powerful PC and then break your school computer over one of the teachers' heads
The desire to force the school to pay for said PC
"Dude, I feel your pain. "
"Fuck this piece of shit. I'm gonna go save up for a better computer"
"Yeah, me too."
