Fatal flaw(s): Expensive, bulky, redundant 

Microsoft had an idea to make everyday household and personal items smarter. Why should your fridge just refrigerate and your watch just tell time, the thinking went. To make that a reality, Microsoft introduced Smart Personal Objects Technology, or SPOT. SPOT would enable any Internet-connected device to reel off information that may be important to you like the weather and stock quotes. The first of these gadget were watches made by Fossil, Tissot, and Swatch. The thought of having your watch tell you what the weather outside is sounds cool until you realize that your phone can already probably do that for you. And like your phone, Microsoft wanted to charge customers a monthly fee of $60 to use the SPOT service. Say it with me: FAIL.
