So what has your experience been with the Moto X on T Mobile? I am very happy with the service, but do not know if I am ready to give up my SD card.
(disclaimer: I'm on AT&T, your mileage may vary on T-Mo but I doubt it) Motorola sure knows how to build a radio. Signal strength on my Moto X is top notch, compared to my LG Optimus G Pro, and is slightly better than my wife's Galaxy S4 also on AT&T.
The loss of the SD card, especially since my plan with AT&T only gives me access to the 16GB Moto X, is very rarely problematic. But when it's a problem, it's a problem. I'd rather have the ability to jack in 32GB even if it was ONLY allowed to be used for media storage. I understand Google really doesn't want to try and support it for storing apps and configuration data, and I get that, I really do - but for stuff like photos and music, an SD card would have saved my bacon a few times.
