I'm really picky when it comes to tech, and I have a really hard time making up my mind. I'm looking for a light and portable notebook, that has a really good screen (ppi, colors, viewing angles, etc) and can handle normal pressure, such as having a few tabs open in Chrome, playing Spotify and some programming (since I'm a Computer Science student and need it mainly for work). I really like the ASUS Zenbook UX350 especially in terms of design, build, size, but I'm concerned about the CPU (800MHz Intel Core M 5Y10). My budget is around $650. I prefer lighter notebooks, but I think I can live with a full size 15" laptop. Screen quality is a priority!
