I have a highschool senior needing a computer and a highschool junior coming up right behind her. I'd like to surprise them each with something but I have no idea what/how to choose. I also need a laptop. I'll use it for writing, picture edits, online browsing etc. Thinking about going to Best Buy but I usually get overwhelmed and end up going with whatever the sales person reccomends. I never feel like I know what I'm getting. What would YOU buy considering the uses?
