Terrence O’Brien, writing for Engadget:
The unfortunate truth is that Firefox OS just doesn’t offer anything that consumers in developed markets want. Nor anything those in emerging markets need. Mozilla can tell us “the web is the ecosystem” or encourage us to “blaze your own path,” but a budget Android handset does all the same things and more. During their shared keynote Kohli turned to Stephen Elop and told him he’d like to see $30 smartphones. If Firefox OS has any chance of succeeding, it will have to deliver a rock-solid browsing experience at prices near that and figure out a way to efficiently manage data consumption.
O’Brien offers a fairly damning view of Firefox OS, the new mobile platform from Mozilla that is built around open web standards. While Firefox OS may be a non-starter in developed nations, will it be able to go head-to-head with the likes of Android in other places? Will its HTML5 apps be enough to take on Android’s massive head start and widespread manufacturer support?
