It has so many features, even a simple navigation system, and it’s battery goes 2 weeks. I love it.&lt;p&gt;I can’t understand why people want to have color, fancy screens on a watch. Do we need colors to see the time? A calendar notification? Heart rate ?&lt;p&gt;A watch should serve information without distracting, and most importantly, I should be able to go out without thinking about battery life of my watch. It should be reliable enough to carry it in the arm.</text><parent_chain><item><author>xorcist</author><text>Why isn&amp;#x27;t e-ink perfect here?
