Eric, meet facts. Facts, meet Eric.
2. "Low adoption rate?" Compared to what? Swine flu? Apple sold 5 million of the things in the last quarter alone, and is rapidly catching up to RIM's unit volume. The 3GS launch was AT&T's highest single sales day ever.
4. You know more than one person with an iPhone. Seriously, you do.
I compare the low adoption rate to the fact that a 30-something old male like myself living in New England who probably, literally, knows several hundred people (count up all my neighbors, family, co-workers, friends, etc) and I know 1 person. Period. That is not an exaggeration. My wife and I both work in high tech...her company is filled with Blackberries and if they don't have a BB they have just a plain old phone (personal or biz use) like a Nokia or Razr. My friend's iPhone was purchased in Fall 2008.
Regardless if the iPhone ever is aimed at business users/corporations, I don't think they are as popular as you think. I certainly do my share of eating out, going to stores, etc. and the people I see are yapping on a plain old phone. Now maybe Johnny's sitting out in the car doing non-talking stuff on his iPhone. I dunno. I have seen, quite literally, 5-10 iPhones in the past 6 months...someone sitting at the restaurant table doing something with it is the usual case.
I think the iPhone's are pretty cool...sweet functionality. But at the end of the day, it's a lot of functionality that I will never use that is being advertised as a TELEPHONE. The iPhone is quite similar to the Touch. I think these similarities and needless apps turns away a lot of customers who want to use it as a phone. But maybe I'm wrong...maybe I will use it for 2 weeks and find that I can't live without it. But it's a HUGE GAMBLE for me to lock myself into a $90+/month contract for 2 years plus $100-$200 for a "phone" that has functionality I may never use (or unlock down the road)...why not just re-lock into a much cheaper plan with a nice free phone (or under $100) that I know does all **I** need it to?
Now...maybe with the iPhone dropping in price this Spring times are changing a bit...and maybe if prices drop more, more people will buy. And maybe as people's existing non-Apple contracts expire they may switch to the iPhone.
I use my cell phone for yapping and texting. I am constantly with my laptop or near another computer...hence no real reason for me to need those features on a phone with an expensive phone plan.
I'd like to see the iPhone open up to other carriers (Verizon) and also have better cell plans (everything usually gets better/faster/cheaper) and cheaper plans. When that day comes, I will revisit the iPhone (just like millions of others will) and see if it's still overkill for "a telephone" or it actually is essential.
Unfortunately for me (and a lot of people in New England) ATT has horrific coverage...Verizon is rock solid. So until iPhone goes on Verizon, us New Englanders who value their service and connectibility will not be buying an iPhone. This probably explains a decent percentage of my statements of me not seeing anyone on an iPhone.
