Apple's launch of the iPad is a gamble in more ways than one.To start with， it's obviously a bet that there are millions of .people looking for a new way to surf the Web， watch movies，and read magazines. But it's also a more fundamental gamble; namely，that people will pay for quality. Starting at five hundred dollars， the iPad is significantly more expensive than its competitors. But Apple's assumption is that， if the iPad is also significantly better， people will happily shell out for it (as they already do for iPods， iPhones， and Macs).That's why when Steve Jobs first introduced the iPad he said that， if a product wasn't \"far better\" than what was already out there，it had \"no reason for being.\"
