iPhone Battery Lasts For Only 40 Minutes Of Talk Time?

The iPhone battery lasts for only 40 minutes of talk time, according to intel tech guru John Dvorak received from an inside Cingular source.

"He says the amateur mistake that they made is not having a removable battery," Dvorak said. "You run 20 minutes and you're using up half the battery power. You get 40 minutes total talk time. And the interface fouls up constantly." Well, this rumor does not do them any good does it? As the article points out there were similar product defects when the new macbooks launched. Could we be looking at similar problems with the iphone? It releases in 2 months. It is always best to wait awhile after an item comes out anyway, as there are always bugs. If this is true, it is a very juvenile mistake and they should have known better. What were they thinking? Is this just the beginning?
