However one of the things that clinched it for me was how much easier it was to setup the Rift sensors than the Vive lighthouses. With the Rift just plug them into the PC and place them on opposite sides of my desk. With the Vive I need to mount them in the corners of my room (what?! yeah, my wife's gonna love that ... not) and somehow get power to them?
That's the ideal setup, but it's not actually necessary to do that. The Vive will actually work with just a single lighthouse, and the lighthouses even have a special mode setting for working in a single lighthouse setting, but you might run into tracking issues, especially if you're playing a room scale game. Two will work at any position relative to you, provided they can detect each other, and should even work if they can't, provided they're close enough to each other to connect via the optional cable you get that plugs in the back of them. As an example, my Vive setup has one of them on top of a small bookcase to the left of my monitor, angled down to point at where I normally sit/stand by simply propping up the back with a book, and another sitting on top of the printer I almost never use, which is on my computer desk, at about a 90 degree angle from the first. This is nothing like the ideal setup, but it works perfectly fine.
