FYI, two more hours have now passed from when I posted that last message, and I literally did not use my phone at all in the last two hours. I was on a job. My battery life has now fallen to 40%. 15% in two hours, and from what I understand, caused by the use of an exchange server email. That's not something I can or would want to avoid, but there are Lots of people out there who have exchange accounts. If Apple wants to be taken seriously by business people, it needs to provide them an option to get their iPhone to work throughout a busy day where the phone is actually doing things not only when it's in the users hands, but all the time like business users expected to.

Every popular product in the world gets some iffy reviews. This one will be no different. You have to understand how to read your typical Amazon reviews. 90% of the people who are going to write a review are the people who had some problem with the device. People who are totally happy with the device don't tend to seek out the place where they can write a review of that product.
