Great article on Steve Jobs, and secondarily, IPhone here.

The article raises all the doubts on the IPhone being successful.  Myself, if the phone works as advertised, there is no doubt it will be a runaway hit.

If it doesn't - if there are major headaches with using the internet, or using a screen keyboard that doesn't give that tactile feedback, and for business users, not having the Outlook synchronization that they need..

Still - no other phone will have a better internet.  Apple isn't only catering to business phone users, but is creating a new market of users. 

So it really is going to come down to, keyboard interface better?
