I think your conclusion about business users may actually be inverted in certain markets. Eg small business in Canada, pre-iPhone the networks have been smoking us on data rates on Blackberry/Treo. iPhone has forced this down. (Pre-iPhone my Treo rate for 8M was pretty similar to my iPhone rate for 2G) From this perspective the iPhone turned out to be a far more productive small-business smartphone for me than I expected.
