Apple just unveiled the newest Apple Watch (we're up to the Series 5 now) and -- I mean this in the nicest way -- but there isn't much to see. Whereas last year's model, the Series 4, ushered in a new, larger screen and a built-in electrocardiogram test, the differences in the Series 5 are difficult to notice at a glance. Chief among them: an always-on display that's constantly visible at dim brightness, but that wakes up to a fuller brightness when you tap it.
