If the excellent performance of iPhone and iPad makes Apple's arrogance almost beyond reproach, then the unsatisfactory iPad will inevitably fall into reality.
Charlie sorrell, an IT product analyst of Wired, a famous American IT magazine, immediately listed the ten missing functions of the iPad: no flash, no OLED screen, no USB interface, no GPS function, no multitasking function, no keyboard, no camera, no Verizon as a mobile operator, no screen ratio of 16: 9, and no high-definition multimedia interface. For users who are used to opening browser, email, Twitter, RealPlayer and Word documents at the same time, the iPad without multitasking function is at best a large Kindle. ?
To be exact, it is far less than the latter in terms of price, 3G, LTE service and standby time. In addition, the size between netbooks and e-books is quite embarrassing, and tablets can neither be placed on the table like the former nor held in their hands for as long as the latter.
Perhaps the weakness of the iPad is that it fails to show the irreplaceability that Apple has always been proud of. At last Wednesday's press conference, Jobs laughed and said that "tablets make netbooks redundant", but consumers' question is, why spend $500 to buy an iPad that is neither easy to use as a netbook nor as light as an e-book?
