Canonical's preview of a smartphone- and tablet-friendly flavor of Ubuntu has finally arrived for folks willing to flash a Galaxy Nexus, Nexus 4 or a Nexus tablet. Shuttleworth and friends stress that the release is intended for developers and enthusiasts -- not those eyeing it as a daily driver, mind you -- and that it's not yet kitted out with its complete functionality. As of now, the Ubuntu touch dev preview contains the shell, core applications, WiFi networking, support for front- and rear-facing cameras and Android Developer Bridge tool connectivity. In addition, the operating system allows Galaxy Nexus and Nexus 4 handsets to connect to a GSM network, make phone calls and send texts. Along with the sneak peak, the Ubuntu SDK has been badged with the alpha moniker since it's flaunting a host of new features, including the ability to deploy and execute apps straight from the IDE.
