I'm seriously considering replacing my nexus 5 with one of these. The only thing holding me back if the lack of LTE. I understand that's a product of the price point. I just like the size of the Motorola phones better.
Before anyone says it I tried the X and four my usage the battery life just wasn't very good. LTE browsing just kills the battery in my experience.
Ya - for me LTE wouldn't be an issue as I'd be using it as a backup phone and not as a daily driver. I jumped back into iOS full force because I missed having an iPhone as my personal phone (required to use them at work) and I couldn't justify keeping a $350 device in a drawer, so I sold my N5.
It'd be a different story however at the $200 price point. Heck - for roughly $300 now I could pick up a Moto G and Lumia 520 and be able to play on all platforms. Would be more worth it to me over keeping a higher end Android cooped up.
Still may dabble with high-end Android in the future - namely when I can really afford to let my hobby run a bit rampant. But for now, my "toys" have to come from the lower end of each platform.
