Rubicon Consulting published data from an online survey of 460 "randomly" selected iPhone users. Full PDF of results is available from Rubicon. They claim there's a 3.8% margin of error with a 90% confidence interval, but the validity of the data depends on how truly random their sampling was.
Summary of results:
- Email is the #1 function.
- iPhone increases mobile browsing with 75% of iPhone users saying it has led to more mobile browsing
- 50% of iPhone owners replaced conventional (non-smartphones) mobile phones.
- 1/3 of iPhone users carry a 2nd phone
- 1/4 of iPhone users say its displacing a notebook computer.
- 40% of iPhone users said "strongly" that they want to add new software apps.
- 40% if iPhone users said the browser has trouble with some web pages they want to visit
A few interesting graphs:Satisfaction
Though iPhone users were mostly satisfied with their units, the two aspects that garnered the least satisfied responses were Battery Life and Wireless data speed.
Own a Mac or iPod Before?
The most interesting statistic from my perspective is that only 25% of iPhone owners owned a Mac before buying the iPhone.
Have you added Apps Already?
This graph shows that over 50% of iPhone owners have added software applications to their iPhone, which implies jailbreaking, but the question doesn't seem to explicit.
How old are you?
