  Will IBM fall?

IBM has over 100 year's history and it faced many tough challenges along the way but every time it came back successfully. This time its revenue dropped 6 quarters consecutively, with the popularity of cloud computing and big data, IBM seems lag behind and is heavily hit by the storm.
