Over the past few years we've seen Microsoft take on the world of tablets with the Surface and, for those who prefer something more on the laptop side, the Surface Pro and Surface Book. But it hasn't truly tackled desktops until today's announcement of the all-in-one Surface Studio. As cool as features like the zero-gravity hinge might be, the Studio will be facing off against established lines like the iMac. We've assembled the specs of some of the leading 27-inch machines on the market and matched them up against the 28-inch Studio to see which is worthy of sitting on your desk.
