I have very limited knowledge when it comes to computers so I really need some help with this SP3 model, which I am planning on buying. I originally had the i5/256gb model but returned it and now I'm thinking of buying the most basic option because I already have a macbook. I'm just going to be using this SP3 in lectures to take notes with the ntrig pen. Storage-wise, I think 64gb is sufficient because I'm only going to be dealing with pdf files. But I'm not sure if other specs like i3, 4gb of RAM, etc., are going to be sufficient for my usage. Any advise would be appreciated Also, is there anyone else using this low option SP3 who would like to share some experience?
