That was a few years ago. I think they are currently about 1% of the market.
It kinda makes all that grand sweeping braggadocio about "the masses" and "for the rest of us" ring rather hollow.
im not sure of their total % but its not very high. If I were them I would be doing everything I could to turn that around.
From the percentages of mac ownership owning a mac is like being gay, whats the % of gay people in the US? like 3% or something?
