Surveys are generally interesting, especially when they deal with gadgets that people commonly use. This time around the iPhone is taking up quite a lot of space on the industry's scene, but while some say Apple's handsets are paving the way for everyone to embrace and ultimately adopt Mac's, (ourselves included) Rubicon Consulting's findings have revealed a totally different story.

According to their survey, iPhone owners aren't, by far, all Mac fans. Just 20% of the surveyed folks said they also owned an iPod and a Mac, while just 5% of the same group of people owned a Mac, aside the Apple smartphone.

That's preposterous! Do you mean to tell me that people aren't taking the bait? Not that Apple sets up traps so people get lured into their world but, come on, you've got to love Macs even more after having a go at iPhone... The answer lies within the same survey, as Rubicon Consulting also revealed that half of iPhone owners are under 30 years old and 16% of them are students.

More than that, a quarter of iPhone users say it's displacing a notebook computer. 28% of iPhone users surveyed confidently stated that they often carried their iPhone instead of a notebook computer.

Other key findings include:
Satisfaction - The iPhone users we surveyed report very high levels of satisfaction with the product; owners use its features extensively.
E-mail is the #1 function - The most heavily used data function on the iPhone is reading (but not writing) e-mails.
The iPhone increases mobile browsing, but also has drawbacks - More than 75% of iPhone users say it has led them to do more mobile browsing; however, about 40% of iPhone users say iPhone has trouble displaying some websites they want to visit.
Carrying a second phone - The survey confirmed reports (rumors) of iPhone users carrying a second mobile phone, either for basic voice calling, or for other functions like composing e-mails.

Rubicon Consulting also found that iPhone increases phone bills. The adoption of the new device costs users an increased monthly mobile phone bill by an average of 24%, ($228 extra per year). It seems they're fine with it though. Premium iPods sound like a fair possibility, wouldn't you say?

The iPhone has also led people to change carriers: almost half of iPhone users changed their job after having got the device.
