The article makes no mention of a phone. That article seems to be exploiting search engines by using the EVO name. It would be nice if they updated phone capabilities. AFAIK the processor is not the most inefficient part of the phones anymore. I know video is hardware accelerated which minimizes CPU. I assume, but don't know, that they have hardware decoding of music as well. Isn't the 2g/3g/4g/wifi/bluetooth radios what cause the most battery drain.
EDIT: Ya that site annoys me. I have seen too much stuff that is inaccurate. I am relatively certain that it was the site I saw that claimed the iPhone 4G was gonna have a reduced screen size.
