This video shows how a 3 year old child get to love Linux in just less than 2 minutes. From the beginning, he is a Windows fan, but when he slowly discovered the beauty of Linux. He could not resist it any further more.

Of course what make him love about Linux not the functionality or open source. It is just the colorful screen and the ability to let him drag-and-drop desktop icons.

Maybe from now on, you should train your kids to love Linux more.

I have been using Microsoft Dos and Windows only ever since I have contacted with computer. There were a few times where I had Linux installed. But in the end I was not satisfy with it. In the end, I had my Windows back again.

Currently, I have Ubuntu 7.04 Feisty Fawn installed on my desktop. It is still in dual boot mode. My desktop is AMD Athlon 2400+ with 1GB RAM and running five hard disks. So far, one of the shortcoming having Linux on my desktop is it does not have Creative X-Fi sound card driver! WTF Creative a big company without any Linux technical support?! Anyway, Creative still promised to delivery X-Fi by around Q3~Q4.

As for my laptop, I would also want to try out install Linux also. But, my works rely heavily on Windows environment. So tentatively, I am planning to install either on an external hard disk or running through LiveCD.
