The Mach's got a 4-inch, WVGA display. And it proves that such a "low" resolution by today's standards can still work on a mass-market device, provided the screen's no bigger than that. It's easy to forget in this age of 5-inch, HiDPI devices.
Android 4.0.4 is on board, and we'd expect a Jelly Bean update at some point, though nobody's saying much of anything at this point. LG's new UI -- is there, so you get a whiff of what's on the higher-end Optimus G, without all the muss and fuss of ridiculously awesome hardware (and the cost that goes with it). Sprint's also living up to its promise to not muck up the phone with too many preloaded apps, smartly tucking them away in the SprintZone app. Sprint ID's on board as well; you can choose to use it, or not.
But the keyboard's the real star here, right? LG's crammed a decent enough slider into a surprisingly thin form factor, with the whole kit and kaboodle measuring in at just less than a half-inch. The keys are decent enough, with a little bit of click to them and some nice backlighting to guide your way.
Also of note is that the Mach's got a removable 1700 mAh battery, so you can swap out a dead one on the go. It's also got a microSD card slot, which helps explains the rather anemic 8 GB of on-board storage. (And about 3 GB of that is taken up by the OS.)
No word on pricing or availability. But this'll be on the lower end of things.
We've got more hands-on photos and video after the break.
