CNET Australia reviews of the Samsung X830 and writes, “All up the X830 is certainly a conversation starter due to its dimensions, music player and the super-quick flick motion it opens with, but there have been a few sacrifices when it comes to usability. It’s probably best to view it as an MP3 player that had a phone function, rather than the other way round. … The compact contours of the X830 make it a conversation starter, but usability has been sacrificed for looks.”

Gizmodo reviews the and notes, “Check out this swiveling MP3 phone from Samsung, the SGH-X830, which is so tiny it would be easy to lose in your pocket. It’s about the size and shape of an iPod nano but thicker. You can swivel the screen around to reveal its phone keypad, whose keys are arranged in an unconventional two-by-two layout. And looky there, it’s a hint of a scroll wheel. Again. Your move, Apple.”
