There was a review the other day at http://arstechnica.com/gadgets/2014/10/testing-a-35-firefox-... (I think this was from HN). I was interested to see how they defined "growth" in revenue figures. It's disappointing to see that they're only stating launches, rather than sales and return figures, and calling that growth. But perhaps it's too early to get real figures right now.
The Good •Per-app privacy controls. Block an app from seeing your location, contacts, or a host of other things on your phone. •It's cheap! •No really, have you seen how cheap it is? It's $35. Off contract. That's like, really cheap.
The Bad •The software—Firefox OS was a totally inappropriate choice of operating system for this hardware. There are literally zero considerations for the speed and memory of the Cloud FX, and most of the device's really serious problems come from running software on hardware that feels well below the minimum spec. •The software (again). •The keyboard—No multitouch, no auto correct, no copy/paste. Press "Q" and "P" at the same time and the keyboard registers "Y." This ruins e-mail, searching, texting, typing URLs, and lots of other stuff. •The memory—The phone constantly runs out of memory and can't multitask. Critical background features like the alarm and checking e-mail don't work because the phone is always out of memory. •The screen—The viewing angles are terrible, and in landscape the shimmery-ness of the display is headache-inducing. •The storage—There isn't any. •The modem—You get Edge data. No 3G. Don't even ask about 4G. •The camera—Pictures look more like impressionist watercolor paintings rather than scene recreations. •The build quality—Ultra-cheap, ultra-plasticky build quality. •The performance—Performance is really inconsistent, but it ranges from moderately slow to I-think-I-need-to-reboot-this slow. •It can't keep time. There's no battery backup for the time, so if the phone resets or runs out of battery, the time defaults to last century. This silently breaks all apps that use a secure connection. •There's no GPS. •Firefox crashes all the time.
The Ugly •Anyone who had this as their first smartphone would swear off smartphones forever.
