A report from researcher Canalys said 13.5 million netbooks were sold globally in the first half of 2009.
Telecom companies have several bundling deals, with about 50 operators selling netbooks.
"Subsidized netbooks have successfully emulated the mobile phone business model, with the market shares of PC vendors impacted "rapidly" by their success in tying up with telcos," according Canalys.
"The "only PC segment enjoying growth this year" has attracted a new category of consumer buyer & forced PC vendors to cut costs, because of its lower price point and focus on mobility," the report stated. "Meanwhile, traditional notebook category leaders--including Lenovo, Fujitsu, Sony and Toshiba--have been slow to recognize how quickly the market is changing around them and as a group they have signed fewer than 10 operators."
The succes of Netbooks also surprised Microsoft & forced them to lower the prices of their XP Home licenses, to regain marketshare over Linux.
Next year about 50 million Netbooks will be sold according to the predictions published in April.
