When I tried on the Apple Watch back on the 11th, I noticed that the Taptic "touch" on the two watches I tried were notably different in strength. I wonder if that was because of two different suppliers or, as I supposed at the time, the difference in mass between the 38mm and 42mm stainless steel watch bodies.
Like Don said, the first report was not an actual Apple release. Who knows if this was an attempt to drop the price of the stock or just someone trying to sow some FUD into the Internet?
You can adjust the tap in your settings on your iPhone. Mine is set to full strength and haven't missed a tap.....and yes it feels like a tap not a vibration.
