There are a handful of reasons that one great PC might not be enough for every user. Some people might have a personal computer and a work computer at the same desk, and others might want to use one of the best Macs in tandem with a PC workstation. I’m in the latter group, since I like to daily drive a mix of Macs and PCs to meet my computing needs. However, using two PCs — whether they be macOS systems, Windows machines, or a combination of the two — at the same desk can be a clunky experience. I’ve had at least a few computers on my desk for years, but I got to try a monitor with a KVM switch for the first time while reviewing Dell’s UltraSharp 34 Curved Thunderbolt Hub. Put simply, it was a game-changer.
