The 64GB Moto X goes on sale in the United States

Want a Moto X(s goog) 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.

Motorola’s next phone debuts on May 13

Motorola(s goog) will add to its Moto G and X handset lines at a London event on May 13 when it introduces “the next Motorola phone.” Invitations for the launch are hitting press inboxes with little detail. One tagline does stand out, however: “Made to last. Priced for all.” That could indicate a more ruggedized edition of the low-cost Moto G, perhaps with water-resistant and dust-proof capabilities. Either way, the handset won’t likely have any influence from Lenovo, which agreed in January to buy Motorola from Google as the phone would have been in the works months ago and the deal is not yet closed.
