6. BlackBerry PlayBook

Date: April 19, 2011

As its smartphone market share began to deteriorate, RIM rushed into the tablet game and invested big in the PlayBook, a business-centric tablet that stood true to the company’s BlackBerry roots. After an uneventful launch, the company had to recall nearly 1,000 devices due to software issues. That was just a smidge of its troubles. The PlayBook suffered from a number significant issues: including an expensive price tag, weak battery life courtesy of Flash integration, a diminutive app store, and the need to be paired with a BlackBerry smartphone to use email and calender. RIM announced only 500,000 PlayBooks had shipped during its 2012 Q1 earnings report.
