I bought a X 700 mobile recently ( about a month back ) . I was waiting for the price to fall below 10K.
Good Features :-
Sound quality is good
A good set of features including MP3/ FM /Speakerphone /EDGE / 1.3 mp Camera/ Micro SD storage , 1000 phone no. storage etc., .
You can have 1 GB of storage in the micro sd card ( I have tried it and it works )- This is different from mini sd card.
However, I am dissapointed with the following :-
Blue tooth hands free does not work with FM radio as well as with MP3. I had read in magazines and web sites that FM radio does not work with blue tooth hands free - but now I find that even MP3 player also does not work. THis was confirmed by Samsung engineer - whom I called up to check.
Overall a very good mobile -with a good set of features . A good buy.
