Marketing Lessons From RIM's Failures

I just read an article about learning from the mistakes of RIM's marketing failures over the last few years.  I have seen the Blackberry's brand value plummet in the last few years and this article outlines the cause as 7 marketing failures and explains how we can learn from those failures.  RIM did not do a good job of STDP their product.  It seems they were trying to straddle the fence between corporations and consumers. They were THE phone for corporations for a while, due to their ineffective targeting, they have lost serious foothold in the corporation world to iPhones.  
Their marketing mix also struggled recently.  They no longer have cutting edge products that were developed how the customer wants them due to a poor NPDP.  They were not getting appropriate voice of customer and turning that VoC into critical to quality aspects of the product.  A combination of poor strategy and ineffective tatics may have been the downfall of RIM.  We'll see how this plays out in the next few years...
