I think historically apple has maintained approximately a 10% market share plus or minus 3 points with a higher share for the US and collegiate market. ChromeOS is supposedly 6% of the desktop market share according to stat counter that I believe confusingly includes desktop/laptop under the same grouping. I'm guessing that about nobody is running chromeOS on a desktop so a reasonable guess is that their share of the laptop market is could easily be 10ish percent. This would leave windows with somewhere between 70% and 80%
