With the introduction of its very own Walkman range, Sony Ericsson has made it a rule to release twin models and what initially seemed to be just minor differences in design and sales package, is growing into something bigger now. When facing off the Z710i and the W710i, we see that the Z-labeled handset for “masses” carries no sporty features like pedometer and calories counter and consequentially, is offered at a lower price, which is reduced even more owing to absence of rubberized casing, unclaimed by the mass market.
