Ubuntu Unity
Thank Jack for the introduction on how to upgrade. I been using Linux for sometime now and when ubuntu introduced unity, it served me well from day 1. I love unity!!. I work as an IT consultant, and have deployed linux into 3 small business. I use to get calls all the time, with previous versions, calls such us, My desktop icon has disappear and can raise an invoice, can't find writer, can't find calc, etc. This are engineering shops, they don't know and they don't care what system they use as long as it works. All of the above issues disappeared with the introduction of Unity. And it is so much easer for training the non technical people, all you do is tell them about the supper key, and to type what ever they want and that is it.
Great job Ubuntu, with Unity I can support linux and keep my full time job!
