i owned moto x with woven black back since august. i was literally overexcieted about wooden backs, and ordered walnut black/black immediately when they became available on jan 21st. but was a bit (...) disappointed when i touched it on jan 25th when it arrived. unfortunately you can't feel the wooden structure. too lacquered, feels more like plastic to me. as i have both phones now, i compared them very thoroughly, and unfortunately (for wood) i have to admit that the grip is much better on the woven black. but i'm definitely staying with walnut back... it looks AWESOME. but also adds a tiny gap between the plastic black (which is actually somewhat blueish in the sun) and the wooden plate, which is a dust attractor... unlike woven back (again) this is somewhat disappointing (no gap at all on that one). if anyone is interested, i can take a few pictures comparing the phones. i bought nexus 5 a few months ago and sold it within a few days. moto x is the best so far: one-palm operation is most convenient as the size fits PERFECTLY, active notifications is the thing you cannot discard after you tried it... etc. i just wish the wood was more ... wooden!
