Apple's CEO has dissed the "limited-function" Kindle Fire

I guess when you can sell 15 million iPads and 37 million iPhones and turn in record revenue and profits, you can feel a little cocky.

Apple's CEO Tim Cook said he didn't see the introduction of Amazon's Kindle Fire tablet having much effect on Apple's sales of iPad tablets

The Wall Street Journal's All Things D reports that Cook said there wasn't an "an obvious effect on the numbers" of iPad sales after Amazon introduced the Kindle Fire last year. Cook added that Amazon might sell a "fair number" of Kindle Fires, but consumers won't be happy with such "limited function" tablets.

On Tuesday, Apple reported that the sales of the iPhone were up 128 percent from the same quarter a year ago. Apple also said it sold 15.43 million iPads during the quarter, a 111 percent increase. Apple blew away expectations with a 73 percent increase in revenue and a 118 percent increase in profits.

Kindle Fire also has been a popular device and some estimates have the tablet selling 6 million units at the end of 2011 and 12 million units next year.

To compete with Apple’s iPad, Amazon has aggressively priced the Kindle Fire. The $199 price tag is less than half than the $499 iPad price.
