Today, our friends at Ars Technica posted a great article, summarizing the two major surveys done regarding the iPhone’s effects: the original ChangeWave survey in August, and the more recent NPD survey. Both suggested that the iPhone is stealing customers from other carriers and manufacturers. And now that ChangeWave has released an updated iPhone survey, we have a pretty good idea of the manner in which the iPhone is transforming the industry.

As you might have suspected, the results look great for Apple and bad for a number of other companies. “Apple has gained a percentage point of manufacturer market share while Motorola has lost a point. Even better, Apple has the highest satisfaction rating (82 percent) of any manufacturer, a number that is 31 percentage points higher than the runner-up, RIM.”

16 percent of those planning to buy a mobile phone in the near future plan to shell out for an iPhone, which puts Apple in the highest “planned purchase” spot; the iPhone also seems to have influenced planned purchases of LG phones and Treos, both of which dropped a few points.

Although the NPD and ChangeWave surveys aren’t directly comparable, both paint a good picture of the iPhone’s effect on the market and reaffirm the notion that it will only be a matter of time before the iPhone becomes a pervasive presence on our campuses.
