"These days it's hard to find a pundit willing to question Apple's long-term prospects or the calls of its famous CEO, Steve Jobs. After all, Apple's fortunes have been on the rise for nearly a half-decade now, and they seem to be only gaining steam. That is, unless you're Clayton M. Christensen, the Harvard professor and author of the seminal 1997 book 'The Innovator's Dilemma'. Christensen, who more recently wrote 'Seeing What's Next: Using Theories of Innovation to Predict Industry Change', isn't willing to jump on the Apple bandwagon just yet. As well as Jobs & Co. is performing now, Christensen fears that success is built on a strategy that won't stand the test of time."
