Cheap, plastic, and good enough: not the best descriptors for something you want to use with your Mac. But AOC’s 16-inch USB monitor, the less than charmingly named E1649FWU, really is “good enough.” It’s an OK second monitor for a laptop. It’s light and the kickstand folds flush with the case, if you want to bring it to a small presentation. It doesn’t need a power cord, the height of convenience. And you can find it online for just $100. But for a price that affordable, you can’t have everything.
