Enders Analysis have released a report to clients on the iPhone: -

"Its reported target of 10 million unit sales in 2008 looks extremely optimistic for such a high-end product with exclusive distribution, with 2-3 million more realistic even if it is a big hit with the target market"
Interesting opinions :-)
