As always with rumors, many questions still need to be answered: When will the iPad mini arrive? How will iOS apps play on a smaller screen? Who will want an iPad mini?

We turned to Kyle Wiens, founder of iFixit, iOS app developer, and a regular Macworld | iWorld conference speaker, for some ideas. His track record for is pretty good. Wiens, of course, agrees that an iPad mini is all but certain even though the late Steve Jobs dismissed such a product as a "tweener"-too small to be a good tablet, too big to be a practical smartphone.

"Steve Jobs always used to say things are lame two years before he did them," Wiens says. "He liked to throw people off the chase."

The Wall Street Journal pushed the idea of an iPad mini front and center earlier this month. Supplier that Asian component suppliers were gearing up for mass production in September of an Apple tablet with a screen size smaller than eight inches. Currently, the iPad has a 9.7-inch screen size.

An astute Apple observer, Wiens isn't convinced of a September launch, which, of course, is only a couple of months away. "I would have seen more parts leaks," he says. "It makes me think it won't be as soon as people want."
