After doing some math, I concluded that the $529 unlocked/unsubsidized Google Nexus One gPhone is much cheaper than it appears to be. In fact it's only $49 when you do the math — and that's unlocked! Google likes to say that the Nexus One represents "Our new approach to buying a mobile phone". But it actually seems as though T-Mobile deserves most of the credit by providing a $20/month discount to customers who purchase an unsubsidized phone — which for some reason didn't seem to get much attention when T-Mobile created the new plan back in October 2009.
