Browser Market Share Equilibrium?
The last months I am frequently observing the browser market share. I have noticed the trend that the browser market share seems to reach an equilibrium. IE is around 58% and Firefox around 32% with small ups and downs. Ever thought Firefox fanatics expect the day that IE will die and their favorite browser will donimate the marker, i believe that this day will never come, at least for the next 5-10 years (Well, i am not Nostradamus 
to know the end of the story). I predict that the market share will be stabilized around today's numbers. Realistically, i do not believe that there are more that 1 to 2 people willing to switch from a browser like IE8 to any other browser.
