Of these no-one is vying more strongly for our attentions than Ubuntu which has continued its breakneck release schedule to today launch v10.04, also known as 'Lucid Lynx'.
10.04 arrives just six months after Ubuntu 9.10 - Karmic Koala - scurried into the wild and builds on the OS's increasingly public persona with a much needed visual overhaul. Most apparent in this is a move away from the turgid browns that screamed "I am niche" to a new metallic, dare-I-say-it Mac OS X look, which I suspect is exactly what it was going for.
Beyond the superficialities 10.04 also cleverly merges Facebook and Twitter accounts directly into the OS allowing users to update either or both from a single window. A new music store brings an iTunes-substitute powered by 7Digital and continues to bundle useful software such as Firefox, OpenOffice and its intuitive Evolution Email which integrates a multi-IM app directly into desktop email - clever stuff.
As always the new Ubuntu claims to operate quickly on any computer and positively race along on hardware this side of the Neolithic era making it particularly good for netbooks. Ubuntu 10.4 is available now and - as always - is free.
Will this finally convert the masses? Probably not quite yet, but it is another important step forward...
