The thing I'm wondering is that I have read stories where this type of characters is typically shown using Macs and related jargon. Though my character is from the US, I'm from Ireland. I'm a CS/Classics student and most of my friends are computer nerds. None of us would go to the Mac lab unless we have to.
Is this a US thing? Are Macs prefered by nerds/cheaper over there compared to PCs? Or is it a factually inacurate stereotype?
ETA: 18 hrs and 55 comments later, I'm blown away by how many people answered. Thank you all so much. in_vino_vanitas seems to have bundled consensus by saying Linux for real nerds, Macs for design nerds, PC for gamers but there are always going to be different computers for different people. As well as this many have pointed out Mac is often seen on TV purely because of product placement, and a lot of nerds build their own PC.
