Plenty of professional reviewers have been criticizing the G4 for not having a "premium" design, instead opting for a plastic design. Do these reviewers not notice that there are inherent tradeoffs with a metal unibody? You lose the removable battery, and then you can't get into the device to perform repairs yourself with ease. You don't need a metal body to have a premium design either. I've noticed that most actual users don't seem to care as long as the device is premium in other areas.
