Sony Ericsson K550 and W660

i've never owned a fancy handphone before...so i'm thinking of indulging myself with one for my next handphone purchase...

i'm leaning slightly towards the k550...specs are almost the same with the W660 heavier by abt 10grams

thinking of ending my M1 line when the contract ends in september and start a corporate plan with starhub...not much perks at M1 and the choice of phones they have so far are mediocre compared to singtel and starhub...unfortunately TOS only allows starhub corporate plans...so not much choice for me also...

but i'll have to wait till september? warao...
