Hi to everyone, I am very interested in the new Surface 4 pro, but I have some doubt about it. First of all, and probabibly the most important question, can the surface replace an ultrabook? What loses, what earns more? My question is due to the fact that I am an university students (engineering) and I need a computer that is ductile, but I also need a computer that can replace, without any difficolties, any normal laptop, because I will use it half at home, so I need a computer that is confortable on the desk, and half at university, so a computer that is easy to have in hands and in the bag. Could you share your impressions and opinions about my question? Sorry for my english, and thanks.
