Cook was responding to a question about competitors during an call with analysts following the company's release of quarterly earnings today. A few months ago Google started highlighting Android apps specifically optimized for tablets at its Google Play Store and, as Cook mentioned, that number is only in the hundreds.
As for the enterprise market, Cook dismissed the premise of a question that Windows 8 and other tablets were making headway with corporate customers.
"We seem to be doing really well," Cook said. "Honestly I don’t see recent announcements [of new tablets] changing that at all. I see more and more people developing custom apps for use in house."
Cook said recent figures show the iPad is being used by 95% of Fortune 500 and 89% of the Fortune Global 500 companies.
An Apple phablet? Now's not the time
Apple's expected to release a new iPhone and iPad later this year, but Cook said that, at least for now, Apple is happy with its decision not to offer a larger-sized iPhone as competitors like Samsung offer, with 5-and 6-inch displays close to the size of a small tablet, or phablet as they are sometimes called.
"My view continues to be that the iPhone 5 has the best display in the industry. Some customers value large screen size, other value resolution, color quality, screen longetivity, power consumption (and other features)," said Cook. "But our competitors have made significant tradeoffs in many of these areas to offer those features. We would not ship a larger iPhone while those tradeoffs exist."
Apple said it sold over 19 million iPads in its most recent quarter, a 65% gain of 7.7 million units from the same quarter a year ago.
