SDG Systems has long offered the useful service of porting rugged Windows-based tablets and handhelds to Linux. Spin-offs include a 2008 port of the TDS Nomad handheld. This time, it’s the Windows 7-based Trimble Yuma 2 tablet that is being tuxified. The supplied Ubuntu 12.04 LTS distro is not to be confused with the most recent LTS release, last month’s Ubuntu 14.04 LTS. The default configuration is a dual-boot system with Windows, although you can ask for an all-Linux look as well.
