the current price of the macbook model on the promo is 2248... and the total amount you'll have to pay in 36months is 3136... so in effect, you'll be paying for ~25+ for your singtel broadband... the rest would be just like paying the macbook... well i think you'd still be able to save on this, 'coz if you buy a macbook with 36month-installment plan and continue to pay 68 for starhub, you'll be paying ~130+ a month...,

If you haven't used a mac before, then prepare to face a little bit of frustrations... i've got friends who are still scratching their heads and tell me, "in windows i can do this and that... how come i can't do it on my mac?" But once you've "acclimated" yourself to using macs, you'll love it...
cheers,
