Want a Moto X but concerned about on-board storage? Well, here’s some good news: Motorola’s started selling a 64GB version for the first time on Monday for $450. Everything remains the same as the 16GB and 32GB variants, except for the increased storage. That’s $100 more than the 16GB version for four times the space. Motorola’s budget handsets, the Moto G 4G and the Moto E, both accept microSD cards, which makes the absence of storage expansion on the high-end Moto X more glaring. We’ll see if Motorola sticks with built-in, tiered storage or if it adds a microSD card slot to the long-rumored Moto X+1, which should be launching this summer.
