Ok, lets get some conclusions about the image:
- Time is 9 years, Linux had almost 9 years old in 1999.
- I don't now the numerical values of the samples.
- In 1999, the average is in medium size (M), in 2008 is extra large (XL).
- I think one explanation, many linux users started as very active-skinny young people and later they gain some weight.
- But really few people, like me, use Linux in 1999, and after the Ubuntu boom in 2005 many new users are converted every year. Are they bigger in size?
- The anti-MS commentary: If Windows crash every 5 minutes, the BSOD makes you move with your frustration, Linux stability makes you be more static in front the screen.
