The device seems priced well, S$248 which according to the site WP7SG is "considerably cheap" as the HTC One X is being offered at S$318 on the same contract.--that's important and good news as the One X is considerable competition.
Nokia's Facebook page did boast the fact that the first five customers to their Nokia stores who purchase the Lumia 900 will get a free Xbox 360 Kinect Holiday Bundle, which is a heck of a deal and some great enticement. Since the 900 is off contract there at the Nokia stores, the price is considerably higher: S$849 at Nokia Store and "approximately S$720 at some stores such as Adix"
Featuring a 4.3" Super AMOLED screen with ClearBlack, 16GB of storage and an 8MP rear camera (plus front facing), the Lumia 900 ships with OS 87730 ("Tango") and should make quite a splash in Singapore.
