As a sleep tech writer, my heart should be aflutter (a problem the Series 12 will pick up on). So why am I feeling... bored?The best sleep trackers offer detailed insight into your rest and there's no doubt the Apple Watch is among the best for accuracy. But the sleep tech market is fast evolving and the bulky, passive Apple Watch is starting to look like yesterday's news.We're still learning just what the Series 12 will encompass (alongside the Apple Watch Ultra 4) and perhaps nestled somewhere in the metrics will be something that will completely change my mind.
