You're right, it's a tough one. Maybe it's fear of the unknown? There's definitely a lot to learn about different disabilities, but so much love to gain too. Your point about sign language is awesome! Everyone deserves a parent who puts in the effort to understand them.
Ooh, that's a tough one! Depends on what you need it for mostly. I'm a total laptop person because I can fangirl over all the groups wherever I am, but for gaming, everyone says desktops are the way to go! What are you using yours for?
