Here is a photo gallery showing the comparison between the Nokia 5730 XpressMusic and Nokia N97. The gallery is posted by Norman over at Symbian World and includes very good shots of the devices. The Nokia 5730 is the first XpressMusic device to be equipped with a QWERTY keyboard.
The Nokia 5730 XpressMusic is very similar to the Nokia E75 and is meant for Music Freaks while the E75 is meant for Business Users. The 5730 has Music Buttons, Carl Zeiss Camera Lens, 15 MB extra internal memory and Nokia Say and Play which enables you to control Music Player using voice commands. The E75 is on the other hand smaller and thinner than the 5730 XpressMusic has better build quality due to metal components.
The E75 and 5730 XpressMusic are siblings of the Nokia N97.
