Lenovo (used to be IBM) has hardly any mobile phones on the market in the U.S. For all purposes, they are primarily a PC/Laptop manufacturer. I think they have 1 current tablet on the market, maybe not even that. Either way it's not really a fair comparison in the first place.
Statistics for you (Apple's mobile division):
Apple currently only has ~25% of the cell phone market with it's iPhone.
Apple currently has ~50% market share with it's iPad.
(These numbers above are the only reason why they are still around)
OSX is currently only being run on 7% of computers worldwide. <--- That's nothing. But they can still turn a profit, since they price gouge every person who buys one.
I find it funny when reading these mobile computing statistics that Apple is only included WHEN they include iPad sales. iPads are not computers, and shouldn't be compared to laptops.
lenovo has about 15% market share.
I'd say 7% isn't that bad.
