I bought the X700 last month and I am very luck to have the phone, to get all the features except 2.0 mp camera and sound volume of K 750i, all other feature is much more better than k750. I reccomond all the people to give a try. It will play some music and video files that other phones refuces to due to error in file and also the PC suite of Samsung is much more better than Nokia Sont Erricsson.
More Taltime and more featues that changes the colour of text which is absent in other phones but there is no themes for this phone. Also the memory card is of latest type. The phone has a descent keypad, no joystick like K750, its a boom. and also there is reserved memory for java. And also there are priviews for Video files which is absent in K750i.
I will give 4/5 points to this phone.
