We've crossed paths with Firefox OS before, but today marks the first time we've played with handsets running the final build of Mozilla's mobile software. The Alcatel OneTouch Fire and ZTE Open you see above are the same hardware we saw at MWC earlier this year -- in fact, the latter just launched in Spain on Telefónica for €69 ($90) contract-free including €30 ($39) of airtime for prepaid customers. We took both phones for a brief spin and immediately noticed a slight improvement in performance. Unfortunately, there's still a significant amount of lag in the UI, especially when scrolling through web pages and navigating the app tray. Websites also take a while to load, even when connecting over Wi-Fi. Then again, what do you expect for €69? Check out the gallery below and hit the break to watch our hands-on video.
Note: the ZTE Open we handled was destined for Movistar (a Telefónica brand) and is launching today for €69 (not €63 as mentioned in our video).
