I am a heavy SP4 user, and I use it heavily for tablets. As a computer I also use it heavily but mostly when connected to my desktop monitor, ie. become my desktop PC. For me the laptop form factor would be useful when I needed a PC for use as a pure laptop, that is, when I needed lapability such as when attending events that don't provide tables, or even when on couch watching TV or just sitting, but for those times when I do need to use a computer (ie. need to type a lot, or do some work). It's at those times that I have found Surface Pro form factor are simply not ideal and feel the need for laptop (for its strong and stable hinge really). I would be installing Windows 10 Pro immediately though.
