The Motorola ROKR E2 is the latest music phone from Motorola. The ROKR E2 runs Motorola’s new 
JUIX user interface, based around Java and Linux, giving us a glimpse of what Motorola has planned in the way of the user interface for the future. Armed with a 1.3 megapixel camera and dedicated music buttons on its sides, the ROKR E2 seems to be ideal for music on the go. It is a tri-band (GSM 900/1800/1900MHz) phone with support for EDGE networks. As well as dropping iTunes compatibility in favor of support for MP3, WMA, AAC, and RealAudio formats through an integrated player application, the ROKR E2 also boasts a few more improvements to things that hindered its predecessor in the past.
Physical Aspects
The ROKR E2 is shaped in a capsule bar form and our review unit came in a funky black and orange color scheme. Ignoring the orange parts, one would be reminded of the shape of the Motorola E1000. The ROKR E2 is solidly built and there were no noticeable gaps, creaks, or squeaks to be found on the phone.
On the front, the keypad is set flushed against the ROKR E2’s body, but I am glad to report that the keys are a joy to use and have good tactile feedback. The 5-way navigational d-pad is flanked by the left and right soft keys, dedicated music key, cancel key, and of course the call and end keys. The end key doubles as the power button. The keypad is backlit with a white light, although I found it to be too dim and uneven. Motorola ROKR E2 Review (MobileBurn)
