hey...i got k550i on dis diwali for 8k (with bill).... n i seriously love dis phone ....heres a mini review :
Pros :
Looks awesome... n unique ... n just 15 mm thick
Really fast interface.... with no lag at all ...even taking pics frm the cam n saving them takes 1-2 sec at the max...
Cam is very gud atleast for me....n after playing a bit with the settings even night pics come alright....n the autofocus rocks.....nwdays i use it instead of a scanner ....
vid recording is ok ... resolutio is quite low but u can zoom them without much distortion
btw it has a twin led flash too...
70mb inbuilt memory + 128 mb card bundled (ya...its 128 not 64)
multitasking possible... u can play games n listen to music at the same time
Decent speakers n i m not a audiophile so even the bundled hpm 62 sounds good to me....u can get hpm -70 if u want wit the extra bucks
U can use he flash even as a torch... might cm useful.....
Battery life is also gr8... hav to charge once in 2-3 days with moderate use
U can flash it to w610i
Cons
The keypad is a bit diff so u might wanna try first...but i got used to them right frm day 1
A bit delicate n is a fingerprint magnet...so get a crystal case
i think dats it...
