Early Lumia 900 adopters might feel spurned knowing that their devices won't get any near-future upgrades beyond Windows Phone 7.8, but AT&T and Nokia are hoping that some new customers just need a little incentive to forgive the OS ceiling. As of now, the Lumia 900 has taken a permanent price cut to $50 on contract, whether it's one of the early color options or pretty in pink. Although the price drop might not take power users' eyes off of the Windows Phone 8 prize, it could make the Lumia 900 a low-hanging fruit for more than a few newcomers.
