At first blush, youd be forgiven for asking what Sonys Xperia ZL was for, given that it was the less fancy version of the Z. The dowdy sibling turned out to be a lot better than expected, however, with nicer ergonomics, even at the expense of the waterproofing. Unfortunately, by the time the ZL was announced, the HTC One (M7) and Galaxy S4 had arrived onto the scene.
