As there are so many phones available, I wonder how much units will Apple target for it's iPhone. I think as the phone is expected in early 2007 and as there are so many competitors around, they will go for a significant sales target.
Considering the current market situation and the number of already established companies around, Apple has to set a realistic target. But of course iPhone will have it's own weight in the market.
I would think that Apple's target is going to mirror what their target is for ipod's. Most people that own an ipod and like Apple are probably going to purchase the phone.
Yes, Apple must be targeting it's customer base of iPod. They will go all out to get the most out of it's user base. I know those who have purchased Apple product will surely wait for iPhone.
