My Nexus S inexplicably went dead on Wednesday evening for the first time ever. I'm guessing it was related to the recent over-the-air upgrade. I popped out the battery and everything is better now. Try that with an iPhone! ;-)
I paid cash for my phone with no-contract with the carrier. I'll break even two months before the contract term would have expired. /me pretty happy with that. Have not suffered from carrier crap, and I can pull the battery! :-)
+M Edward Borasky T-Mobile was $25/month for unlimited data. I declined the text plan, so I pay by the text. It would be unlikely for me to do 50 texts a month, which is the break even quantity. If I have tubes, googlevoice does my texts for free.
