"Canonical's Ubuntu 6.06 LTS is an excellent Linux-based operating system - so excellent, in fact, that it not only earned eWEEK Labs' Analyst's Choice designation but has also become our clear favorite among Linux desktop distributions. This latest Ubuntu release, which became available in June, has won our ardor with a tight focus on desktop usability; an extremely active, helpful and organized user community; and a software installation and management framework that's unsurpassed on any OS platform."
