Difference between K550i and K750i

[nilesh5647]

I am going to buy new mobile phone and wondering which one to bye K550i or K750i
Is there any technical difference between this two mobile except its looks and design and
specially its 2 mega pixel camera?
Is it true that k550i keypad is brittle and not good for texting?

EDGE available only in K550i.

k550 is slimmer and lighter, has a cybershot branding, accepts m2 memory card instead of mspd in k750, internal memory has been increased to 64MB, has a2dp, has a different screen and has edge
yup k550 keypad looks odd

550i has EDGE , cybershot branding [ though it does not fully live up to it ] , more feature packed .

It's got more internal memory, uses M2 memory card( which is more expensive than the card the 750i uses ) , has a better screen .

And the keypad is different but i did not find it uncomfortable at all .
