Gartner reported that PC shipments totaled 80.3 million units in Q3. Subtracting an estimated 4.4 million Macs yields an estimated 75.9 million Windows PCs.

This total is lower than the total shipped in the same period of 2008.

The graphs above show the Gartner data and the split between tablets and PCs.

If we include all iOS and Android devices the “computing” market in Q3 2008 was 92 million units of which Windows was 90% whereas in Q3 2013 it was 269 million units of which Windows was 32%.

Any guesses on what this market will look like in 2018?
