> 1. Refresh time on turning pages
It takes me just about the same amount of time to flip a page on a dead-tree book as it does for me to wait for the next page on my Kindle.
> 2. Price
It's still early adopter time. Re: the innovator's dilemma - it will be expensive at first; that is expected.
I'm surprised how little (if anything) I've heard about the iPhone being the catalyst for mobile viruses. You know the iPhone will get cheaper and with Cingular/AT&T subsidies, it may gain a very large "surface area" and that is what is attractive to virus writers: that and the notoriety of being the first (or one of) to unleash a mobile virus into the wild. Clamping down the OS will help protect (at least for a short while) the iPhone from the nefarious fate that will eventually be bestowed upon it.
The (somewhat controversial) web-usability expert, Jakob Nielsen, has had much to say about response times. From his 1994 book, Usability Engineering, he states, "10 seconds is about the limit for keeping the user's attention focused on the dialogue." (reference: http://www.useit.com/papers/responsetime.html). You may have heard of him through his 2000 book, Designing Web Usability: The Practice of Simplicity. There has been a lot he has written that, in light of new methodologies, still makes good sense/practice.
