Amazon Kindle Tablet at $249 Beats iPad at $599

Amazon's Kindle Fire will be unveiled in New York City tomorrow. Piper Jaffray said the tablet could be super popular for consumers desiring a low-cost portable computer.

If Amazon (NASDAQ:AMZN) should sell its first tablet computer for $249, it will easily become the most successful alternative to Apple's (NASDAQ:AAPL) iPad, according to financial services researcher Piper Jaffray.

Piper Jaffray analyst Gene Munster polled 410 U.S. consumers last week and found that 62 percent of those surveyed said they would pick a 7-inch Amazon tablet that costs $249, compared with 21 percent of consumers who said they would pick a 9.7-inch iPad that costs $599.

"We believe this shows there is a high degree of price sensitivity in the tablet market," Munster wrote Sept. 27 in a research note. "Tablets are mostly supplemental devices (in addition to a computer and a smartphone), so the data makes sense."

Amazon is expected to unveil Kindle Fire in New York City Sept. 28. It's a 7-inch slate based on Google's (NASDAQ:GOOG) Android operating system and built by Quanta, which makes the RIM (NASDAQ:RIMM) BlackBerry PlayBook. Many of the tablet's features have been unearthed by TechCrunch, though the device's cost remains a mystery.

Amazon could sell the Kindle Fire for anywhere between $250 and $400, a bid to properly challenge the iPad, which has sold more than 30 million units at a base price of $499.

However, the industry consensus is that Amazon will be most aggressive in its pricing, hoping to make up the low price point of the hardware with sales of movies, music, storage and other content services.

For his survey, Munster used the $599 price point of the iPad 2's 32GB version instead of the $499 $16GB base model because he said it's an estimated average price of $599.

Munster also offered the caveat that his survey comes with the Kindle Fire sight unseen, and he cautioned against putting too much stock in his poll until the public knows more about the device.

That should come tomorrow morning in Manhattan, where Amazon CEO Jeff Bezos will show off the device, which is based on a custom version of Google's (NASDAQ:GOOG) Android operating system.

The Kindle Fire is expected to push users toward Amazon content services, including the Kindle application for books, Amazon Cloud Player for music, Amazon's Instant Video player for movies, and the Android Appstore for mobile applications. Munster noted that respondents' uses for tablets included Web browsing, reading, movies and games.

"If Amazon can do these four things at the $249 price point, we believe there will be strong interest in the tablet," Munster added.

To that end, Munster said he expects Amazon to sell 2.5 million Kindle Fire tablets and an additional 3.5 million Kindle e-reader devices in the December quarter. The company's Kindle brand will account for $5.4 billion, or 8 percent, of Amazon's total revenue.
