Mac market share jumped just under half a percent in November to 7.3% - 3.28% PowerPC and 4.2% Intel Based Mac's. It was the second biggest gain for Mac market share since the transition, the largest being .55 percent at the end of January last year. If the numbers next month follow that trend, it's just barely possible that the Mac platform could break 8 percent. At any rate, sometime in 2008, Mac market share—and by that we mean growth, not installed base—will exceed 10 percent. That's right: according to the metrics derived from web usage as indicated above, one in 10 PCs will be a Mac.
