The Asus Zenfone 2 is one of the better mid-range unlocked phones out there thanks to the robust Intel Atom SoC lurking within. Now it looks like there's a new version of this device that ships with 16GB of storage and 4GB of RAM. It's selling for $229, which is a pretty good price for what you get.

Thus far there have only been two versions of the device—one for $199 with 16GB of storage and 2GB of RAM, and another at $299 with 64GB and 4GB. There are two different Atom SoCs used in the Zenfone 2, and the new $229 device appears to have the slower of the two (Z3560).

So you get a lot less internal storage in the new Zenfone 2 compared to the $299 version, but the price is only a little higher than the one with 2GB of RAM. That might make it worth the upgrade. This phone has a microSD card slot, so you can always add more storage. The phone is listed for sale on Newegg, Amazon, and B&H Photo.
