What the heck are you talking about? <-- Note the pretty pie chart.
You're ridiculous. The chart you started this thread with is GLOBAL market share. The blurb clearly delineates US-based market share preference for the iPhone, and given AT&T is a US-based carrier, the share of Symbian OS globally is a silly thing to compare against. Note this chunk:
"Considering Apple's gadget is currently the most popular handset in the U.S., its exclusive carrier's inability/unwillingness to support the device in the country's largest market is pretty huge news. If this proves true, I'd expect curtains for AT&T's exclusivity deal when it comes up for renewal.""
OK, here's the US-based share: http://www.boygeniusreport.com/2009/10/28/rim-and-apple-top-u-s-smartphone-market-share/
Given this, RIM is actually the favorite. I did no digging into the source of the data, but it appeared in numerous places and seemed to be well reviewed. It does not include Droid as it was published in late October 2009.
It also proves wrong the 1-2% commenter. iPhone is quite popular in US, but RIM still holds the edge.
If you are good, you will be assigned all the work. If you are real good, you will get out of it.
