Sounds like my vision test is working.
Oh and your link? Here's a quote lol
"In 2018, the main players in the smartwatch market were Apple, Fitbit, Samsung and Garmin. Apple entered the smartwatch market in 2015, launching its highly anticipated Apple Watch, which now dominates the market.
More than 9 million units of the Apple Watch were shipped in the fourth quarter of 2018, making up more than 50 percent of the global smartwatch market share. In comparison Samsung shipped 2.4 million smartwatches during the same period, a market share of about 13 percent."
