Apple begins taking pre-orders for its new Watch today. This stylish watch includes the ability to track your heart-rate, use ApplePay, view text/email messages and take calls Dick Tracy-style by speaking into your wrist (so long as the Watch is linked to a nearby iPhone). This product launch is unusual for Apple because it is offering a wide range of styles via a combination of options: two types of Watch case sizes (38mm, 42mm), three different Watch cases (stainless steel, aluminum, 18 karat gold), and a variety of Watch bands.
