Just got hold of the new Forerunner 110. Gone for the grey unisex model as it'll have more market appeal if I go on to sell it in the future. First difference is the charging clip has 4 connections - not the 2 found on the existing Forerunner 405 models.
The existing 2 pin connectors can be used to charge, but the 4 pin one is needed to sync the data - The Forerunner 110 doesnt use the Ant wireless stick.
First run with it this weekend so will compare the new model to the 405 soon..
