Barron's is reporting that an un-named analyst has seen Apple's forthcoming tablet and expects it to be announced in September with a ship date around November. They mention that Apple is such a bellwether for the industry that all other manufacturing in this area has stopped until Apple releases this product. They expect the product to retail for $700-$800 and fulfill a variety of multimedia functions including AppleTV and Gaming.
One veteran analyst who has seen first-hand a prototype slate-style computer from Apple says the device could be announced in September for release in November.
