Many people are excited about the PlayStation 4 Pro, which I just unboxed. But not everyone is set up to take advantage of its 4K video, which requires an expensive 4K TV. But regardless of your television, the PS4 Pro does have some nice features, such as higher framerates, 802.11ac Wi-Fi, and a third USB port. To help you decide whether to buy one, I offer my advice to potential buyers in each of three categories: those who have a 4K TV; those who already have a PS4 but not a 4K TV; and those who have neither.
