Is the world ready for a Microsoft (MSFT 0.37%) smart watch? Sources tell The Wall Street Journal that the software giant is starting to stockpile supplies to enter the market. 

Wearable computing is clearly going to be a big market. Google's (GOOGL 0.55%) push for high-tech glasses is the real deal. This isn't science fiction anymore. Samsung last month announced that it's exploring a smart watch. Then we have Apple (AAPL 1.27%), which has long been rumored to be working on a smart watch.

Given Apple's anemic share price, the hunger for innovation could make an Apple smart watch hit the market sooner rather than later. The surprising success for Kickstarter-funded Pebble naturally has Google and Samsung thinking of ways to exploit their successful platforms through Bluetooth-enabled watches.

Microsoft is in for an uphill battle. In this video, Rick Munarriz explores the three reasons Microsoft's smart watch is likely to be a dud if it ever does hit the market.
