Feel free to browse through my portfolio, which contains selection of works that I did under How a computer affected my life
My 3 years old Acer Travelmate runs at 512MB. As it is getting older, I am having a hard time running Adobe Photoshop, Adobe Illustrator and Windows media player at the same time. If I open 2 programs together, it works very slow like an old granny at a marathon run. A four hours Photoshop work has become an eight hours work. I become grumpy and the unwelcome-wrinkles comes out.
It is a relief when I got my Dell Inspiron 530 a month ago. Although it is only Dual Core and the computer memory is just 1GB, but it is good enough to run Adobe software and listen to mp3 at the same time. Good performance of the computer resulting in good mood. Good mood means can produce better design work (and finish in a short time) and blog more. The end result is, more $ money $ comes in which means better life. 
I always use Adobe illustrator at work because i work in an animation studio. this is really a serious tool for the graphic artist.~*:
