I've been a Motorola fan, having owned the Droid Razr, Maxx, T1 & T2. With that said, the S7 gets you a great camera, water resistance, wireless charging, etc. Now, it appears, you will have to pay extra for several of those features on the Z, AND you won't be able to have them on the phone at the same time. The key will be the price. My guess is that even if the price of the phone is lower, by the time you slap on a couple of the mods, the total price will be higher. If Moto can sell it, more power to them. Time will tell.....
