Thanku for the response me too, may be I will get one now, and the other one I will get sooner- consderinig that I have only 15GB of music, I don't see a any other need of the 120, but there another factor! volume is very very very important for me.. I am hard of hearing... It really matter a lot if there any diffrence in volume level sound and makes the choose more easier.
Please consider sevrel headphones and not only one..

Continued from last message: Being the J3 is very responsive, even the slightest touch on the wrong selection occurs for me. Flash games should be a lot more fun to play on the J3 because of its tilt sensor, which seems to be absent in the X7. Of course, the X7 is much larger than the J3 and heavier also. I think I am keeping the X7 due to the extra storage space and battery life, but if I could I would hold on to both players because each one has its own set of advantages.

Hi, in regard to your message, I think the UI of the J3 is more polished and is easier to get around because of the capacitive touch screen. The music's settings are a bit more easier to control because it is done by tapping the now playing screen with all the settings readily accessible. The X7 is almost just as easy but the settings are on the bottom of the now playing screen and doesn't seem as nice to use. However, the X7 is more customizeable, especially with the availability of widgets that can be placed on the home screen for additional functionality. I also find I am makeing less mistakes in selections of the X7 due to the larger screen size and the slightly less responsive screen.
