Just to be redundant... 4k TV's are CHEAP now (and can obviously be used as a TV when necessary). However, you DON'T need to use the 4k resolution! I use mine at 2k and everything is just so much easier to see. Sure, you can dedicate different areas just as if you had multiple monitors (see links above), but then you also have the luxury of using the whole screen whenever you want - something that's not really possible with dual monitors (unless you like ugly bezels in the middle).
