i bought k300i 2 weeks back for 6.1k
the keypad is quite good, especially the joystick is very very soft....after using it, using the joystick of 6600 became difficult.
one odd thing abt this phone is that some wav files play and some dont.....
the camera: the resolution is good upto 1280X960 resolution. but when i click the pic, the phone moves a bit and the picture comes bad...also sometimes i feel there is a lot of light in the picture..
but the best thing of this phone is its speakers, although u wont be able to put a lot of songs in this phone, but still listening to music is gr8 experience in this...even when i call someone who has a RING BACK TONE with good beats, it sounds really nice, i compared calling the same guy from k300i, ngage qd and a landline phone, and the sound of k300i is really superb....the media player also has a equalizer in it.
