The latest release of Ubuntu (9.10, aka “Karmic Koala” came out yesterday, Thursday 29 October 2009. I’m a big Ubuntu fan, and although I haven’t tried Karmic yet, I can still predict it’s great, and I wholeheartedly recommend it to anyone who longs to be free of Microsoft shackles and is thinking of migrating to Linux. Take the plunge! You can find links to download Karmic here. I suggest that you get the .iso over bittorrent, to avoid the inevitable congestion at the Ubuntu servers (they’re always very busy just after a new release) – click here to find links to the torrents.
Once you’ve installed Karmic, there are a few more things you need to do if you want to play mp3s, movie DVDs etc. There’s an excellent guide on this kind of stuff here. It’s all pretty easy and guide describes it all very clearly.
Ubuntu is a great alternative to Microsoft Windows and Apple Mac OSX. You really ought to try it out; and the live CD image let’s you run it in RAM without needing to install to your hard drive, which means it’s easy to check it all out before installing. So go on! What have you got to lose*?
