At 15.6 inches I think it depends pretty heavily on how good your operating system's font rendering is. If you're stuck on Windows I can't imagine using anything lower than 4k at that size. On the other hand, I'm using a 17.x inch laptop currently, only about a foot and a half from my face, at only 1080p, and it's fine. (Before you blame my vision - I'm actually nearsighted. My vision is near-perfect at this distance.) I certainly wouldn't accept this DPI from a current laptop, of course; the font rendering certainly could be a lot better and more density would be nice for easier photo editing and so on, but I think a lot of people have forgotten just how good 1080p can be if it's handled well in software. A whole generation spent most of their time on crappy CRTs. Compared to that almost any HD screen is an enormous improvement.
