Making a complete switch to Linux/Ubuntu

It has been one week since i broke my internal hard drive of my laptop. I bought a new one and got it installed. One of the damn thing I have to face was that the data in the hard drive was irretrievable. That means only one thing-all the documents, photos, audio and video files I had been saving on the laptop are completely wiped out. Yeah......?! And one of the downside is i have to do the system installation all over again. This time, however, i decided not to dual boot my system (XP+Ubuntu). I just did a fresh installation of Ubuntu. Completely dumped Windows. Yahooo.... Now say goodbye to the Windows, and say hello to the open-source world. Yeah, one more thing, I also decided to dump QQ since i already forgot the password. So, also say goodbye to QQ.
