Ive been using this phone since last 6 months and except for the sound quality, there is nothing I cant complaint of. Prior to this, I used the previous version of this smartphone from Motorola - MPX200 which had frequent hanging problem.
The processing is fast (though the start-up is slow) and applications start up quickly. Comes with Windows Mobile 2003. The camera quality is fine if you use it outdoor (indoor camera output is so-so). Battery works fine for me for about a day and half with heavy calling and gaming.
Comes with a USB Data Cable (works also as a USB charger) and Windows CD. Has IR and Bluetooth. The only drawback is the voice quality which is not as good as other Motorola Phones. Again this is a quad-band world phone.
Id recommend this to others and specially Nokia fans.... offers a lot more than any Nokia phone.
