Technically speaking, there have been no sweeping changes to the Business Desktop Remix since we evaluated it when it was first introduced in February 2012. It remains essentially a spin of standard desktop Ubuntu, with games and other leisure software removed and replaced with tools more likely to be of use in the workplace (presuming workers actually aim to be productive, of course — otherwise, the business remix may prove a major disappointment for those accustomed to screwing off at the office).
But the latest release of the Business Desktop Remix, which debuted on May 10, is updated with all the more general enhancements of Ubuntu 12.04, the most recent version of the operating system. It also marks the first longterm support (LTS) iteration of the business remix, and as such will likely enjoy greater appeal to enterprise users who want to stick to Ubuntu releases with long support life cycles.
