Is the K750 by Sony Ericsson any good?

ive always been a nokia man but my last one (6101)died prematurley and i payed wayy 2 much for it in the 1st place. anyways Optus is advertisin the k750 for $199 prepaid; as i got no experience with S.E's i was just wonderin if this is a good phone?? i want a phone that can take a few knocks, and has an intuitive (easy to navigate) menu like nokias. thankkssss!!
