Apple about to launch a new 15 inch laptop

Apple is conducting the final testing stage for a line of ultra-thin laptop 15 inch size.

Not clear this would be a complementary product line of ultraportable Apple MacBook Air (the only version of 11 inch and 13 inch), or an entirely new product line.

MacBook Air is now considered the strategy on Apple's laptop market. This laptop was recently upgraded last week, armed with 2 CPU generation of Intel Sandy Bridge, high-speed data transfer port Thunderbollt, OS "lion" new Mac OS X Lion and backlit keyboard. Meanwhile, high-end MacBook Pro laptop line has just been upgraded in February.

Many thought that Apple's new 15 inch model is a hybrid product, carrying the thin design of the MacBook Air and the processing power of the MacBook Pro.
