Amazon may be late to the smartphone market with its new Fire phone, but it clearly thinks it can do better than Blackberry. Blackberry once owned the mobile phone market, but has never recovered from its decision to keep the keyboard. Ari Zoldan, CEO of Quantum Networks, says the key difference between the two companies is that Amazon has the safety net of its retail operation to fall back on, whereas Blackberry's sole business is the phone. Zoldan says Blackberry isn't going down without a fight though, in its latest earnings report the company said it sold 1.6 million phones. Debra Borchardt reports from Wall Street.
