According to a recent study by Net Applications, OS X Lion’s install share has almost reached an equal with Snow Leopard.
Snow Leopard still has the majority with 43.64%, but Lion is catching with 39.6%. At it’s current rate, Lion should surpass Snow Leopard by spring, just in time for Apple’s latest OS release this summer with Mountain Lion.
Another interesting point is that Leopard still has an installed base of 13.5%; showing that there are still older Mac’s out there running happily.
Long live the Mac!
