Thanks Macros, actually you read my mind. I was thinking to dedicate a computer to experiment with new things related to Linux. I believe Ubuntu is a version of Linux, right? This situation with the N900 exposed me to new thing or better said new terms that I still don't understand but will soon like "an image" or "a mirror" . My personal philosophy is to survive in a world without Windows or Apple. Windows because it charges for everything and it is full of viruses and Apple because I hatted their company strategy from the beginning. They built their machines to be compatible only among themselves while Nokia was the other extreme. That s why I loved Nokia phones till they merged with Microsoft. Then I went with Samsung and now Imnth8nking to go back to Nokia again. Anyway ....yes I th8nk I 'll start my learning process into Linux. Thanks again for being so suportive
