I am selling my surface pro 3 that I’ve used through out university. It’s an older model, but surface pro’s have been known to last a long time. I’ve mostly used it with the charging cable connected, so I can’t comment on the battery life. It’s good for canvas, blackboard, or schoology as well as light web surfing, youtube videos, streaming, and some light gaming (League of Legends plays on around 40~50fps). It does have a small dent in the left top corner as well as a thin transparent yellowish line that goes from top to bottom (it’s hard to tell unless you’re on a website that is completely white), but everything still functions well. The keyboard is also back-lit and unlocks the computer with fingerprint. It will come with the surface pro 3, keyboard, charging cable/adapter.
