I continue to read people discuss wether to get the thunderbolt now or the bionic later. It has left me with a question. Let's assume I buy the thunderbolt now on a 2 year contract. Say the bionic comes out 5 months later and I purchase the bionic and sell the Thunderbolt. I am making a guess that it could sell for say $400. So that would make the costs: 2 year contract - $250 for Thunderbolt? $350 ETF (5 months x $5/month off $375) $400 for Thunderbolt off ebay. By my calculations it ends up costing $200 to have the thunderbolt for 5 months. But with the higher retail cost of the thunderbolt maybe it could sell for 450/500?
