There is an oft quoted statistic stating that Apple has 3-5% market share. What does that mean? Does this mean that 3% of all computer sales in a given year are from Apple? Or is this an estimate of the total number of Apple computer users (worldwide, national, etc.) in a given year? So, what, in your humble opinion, is the estimate for total percentage of computer users that are Apple users? It seems to me that if is the sales per year (most likely the 'real' meaning of the stat) then in any given year, the total number of computer users that are Apple users should be more than 10%-20%. Now Windows would have about 80% of the computer users, while Apple and Linux would make up the rest. What are your estimates and remember that anecdotal evidence is usually next to useless. (i.e. every one I know owns a Mac therefore the percentage is 100%.) And is there any published stats out there that would be helpful. Why is this information helpful? Because like Ghz, market share quotes on durable items can be misleading. Few people can buy a new computer, car, vinyl siding, etc. every year. Trends over a longer period (say three to four years) of time would seem to be more helpful and can negate statistical "noise" like economy in recession, new product releases etc, fluctuations in component prices (memory, LCD and other components that affect the price of the computer). I would appreciate thoughts on this.
