i am absolutely new to Ubuntu and i don't really know what to start with. Could you give me some ideas? What applications should i install first? I install it on a laptop with window 7 on it. I often use it for photo and video editing, coz i love taking photos, as well as audio editing (i am using adobe audition on win 7), and also making powerpoint slide(which i want to do the more coz sb said it's much easier to make slide via Linux), thz a lot.
