Goldman Sachs has a new report out on the tech titans' competing platforms and ecosystems in which it starkly quantifies Microsoft's loss of share among computing devices over the last decade.
According to the report, Microsoft's operating systems have gone from 97 percent of all computing devices in 2000 -- back when desktop and laptop PCs were dominant -- to 20 percent expected in 2012 -- when PCs, tablets and smartphones are all part of the computing-device picture.
Here's a chart from the report showing part of that shift. (The chart shows consumer computing devices, rather than total computing devices -- which includes both consumer and commercial. That's why Microsoft is shown is having 93 percent in 2000 in the chart, as opposed to 97 percent.)
