Apple rose to the top, from third place last year, because the Cupertino, Calif., firm "loudly discovered an empty space in the computing category that it filled with a new device -- the iPad," the report said.
"In the last quarter of 2010, Apple sold more iPads than Mac computers. The iPad, which quickly met competition from other tablet makers like Samsung, helped Apple pass Dell and HP in total portable computer sales. An Apple cloud would further strengthen the brand as a trinity of platform, content and device."
It was temporary thing due to that apple was first who filled market with iPads and that doesnt say anything mate
I am not saying that apple is bad company, I am saying that Android is new OS which is great competitor for iOS
How long iOS took time to grow the market?
Now check how long Android took time to take the market?
Every new device is now mostly occupied with Android
More users, more support, more development it grows fast....
