I always tell people, for the cost difference just buy a fully articulated TV mount. Even if you never intend to move it around, having a simple way to get to the cabling for the TV makes it invaluable.
I love how flat this mount is, but the little things are what really make it shine. It comes with a paper template for drilling the mount holes, so you just tape it to the wall, drill, and can screw in the mount. This review took me longer to write than it took to mount the TV on the wall.
I won't even consider using a TV mount that doesn't come from Monoprice. You just can't beat the price, value, and feature set.
