Verizon today stirred controversy by launching Microsoft's Kin phones on its network with high costs. Despite carrying a feature phone OS, both the Kin One and Kin Two will require a full $70 smartphone plan to use. The prices are also in smartphone ranges and put the One and Two at $50 and $100 respectively on contract, but only after a $100 rebate on each. Both go on sale May 13th.
