Almost two years ago Apple Insider‘s Kasper Jade reported about a forthcoming larger-than-iPhone Apple device that he described in a headline as “a return to the Newton.” Now he’s describing Steve Jobs’ latest brainchild as “a 10-inch, 3G-enabled tablet, akin to a jumbo iPod touch.” It’s going to cost maybe $450 or $550 — “somewhere between the cost of a high-end iPhone and Apple’s most affordable Mac notebook” — and will most likely turn up any time between January and March 2010.
