Let's take a moment in our delicious iPhone insanity and rumormongering adrenaline rush to be realistic here, to intelligently compile some facts and draw some educated conclusions. The iPhone can never be bigger than the iPod. The iPod has sold 100 million units, is accessible to at least 8 languages, almost all sentient languages, and people in dozens or hundreds of countries. (Not to mention people who may be able to afford a $200 DAP but not $2000 over the course of a couple of years.) Rival research firms IDC and IDG news report slightly different realities on unreleased numbers of current subscribers, with AT&T having the #1 spot as largest provider by millions of wireless subscribers, with 62.2 mil, but IDC reports that they only have 56.3 mil subs (making them #2). Last quarter, they gained about 10-12% growth. The same research firms estimate that there are about 236-250 million wireless subscribers in the US. So obviously this means that estimates of the iPhone giving AT&T 1-2 million customers is completely realistic, but if this 3-5 year AT&T exclusivity contract holds true, we won't see the same explosive growth as with the iPod (especially post-nano). Worldwide, in 3-4 years, we might see 100 million, but only if Apple significantly fleshes out the iPhone family to attract and keep a larger target demographic than luxury high-end smartphone users AND they release the iPhone in Europe, Asia, and other GSM markets such as South America. What does this mean to you? Probably a phone-less iPod, if they do not want growth to become stagnant or to lose share in the DAP market.
