Have Apple’s iPhone and iPad saturated the U.S. market? by Philip Elmer-DeWitt @FortuneMagazine December 17, 2012, 5:21 PM EST E-mail Tweet Facebook Google Plus Linkedin Share icons Click to enlarge. FORTUNE — “Despite concerns to the contrary,” writes Morgan Stanley’s Katy Huberty reporting the results of a proprietary survey of 1,000 U.S. consumers, “iPhone and iPad demand remain strong. C4Q US iPhone purchase intentions beat our forecast. Stable 50% iPad share also surprised us, despite our modeled drop next year.” Among the key findings: Strong iPhone 5 demand. Survey suggested 33% growth year over year, and growing numbers of buyers favoring higher-priced models. iPad Mini cannibalization concerns overblown. 47% of iPad mini purchases are to new customers, only slightly lower than the 56% for the larger iPads, suggesting manageable cannibalization risk. Apple holding its own against Samsung. “Rising Samsung share is at the expense of other Android Smartphones and tablets as iPhone share of new purchases is also expected to rise (4 pts) over the next year.” Apple a clear winner during the 2012 holiday season. Tablets are the No. 1 gift idea in consumer electronics this year, edging out e-readers. Apple AAPL ranks highest among vendors at 38%, up from 34% last year. Huberty’s report is filled with charts that bear a close look, starting with Figure 1, below, which shows U.S. iPhone sales hitting new records despite continued market penetration and year-over-year growth numbers that have come back to earth.
