Apple needs Hercules for advertisement
Here in Canada I used to work in an awful convenience store, they had a tablet -- PC based. This was used for ordering, checking stocks, and other business related applications. Virtually, all convenience store in Canada and America have similar tablet.
Apple will have hard time popularizing "iTablet".
Here are two simple reasons:
#1 Business community prefers tablets with "changeable battery". Apple hates giving such option to their customers. Steve Jobs would gladly throw his grandmother to the wolves than give loons option of changing gadgets’ batteries.
#2 Business community desire matte screen tablet -- all apple products including iPhone are "glossy". With iPhone it’s hard to see during bright sun light. This is why Blackberry can not be replaced by iPhone. MacBook, iPhone, iPod Touch are so reflective that you can use them as shaving mirror! Until, last years they didn’t believe in “anti-reflective” LCD. Sadly, problem still persists, and Apple in their “democratic” way is “reasoning” with unhappy customers.
As you can see, this device is already in use in business community. In today's economy with Apple's pricing is not going to be easy -- save for few Mac worshipers.
