It's bound to happen: iTunes is now the largest music retailer in the US, knocking Wal-Mart off from the coveted pedestal. Coupled with the immense popularity of Apple's iPod portable digital music and even the iPhone, you can bet that we'll see more of iTunes for more years to come.

According to numbers released by the NPD Group, the worldwide market of laptop notebooks saw a 14% rise in Apple shipments since last month. And better yet for the Cupertino-based company, 14% of all notebook computers sold last month were also Apple-branded.

Analysts believe that this may be an indication that the laptop community is embracing more and more of Apple, despite being only fourth place in the current generation laptop race in the U.S. Hewlett-Packard, Gateway, and Toshiba sit at spots above Steve Jobs' company, as reported.

Further consideration of Apple's year-on-year growth, however, may drive the company to steal the third spot. The May figures actually represent a 65% jump from Apple's figure last year, and if Apple can keep that year-on-year rate up for the next month, the numbers would spring the modest 14% to a proud 20% in just thirty days.

Apple grabbed 9.9% of the laptop market last March besting Compaq which only posted an 8.5% showing. This feat has put the company at fourth place in NPDs list of highest selling vendors of retail notebooks.

The companies that were ahead of Apple are Gateway(13%), Hewlett-Packard (23.9%) and Toshiba (26.2%). Apple's sales posting is up from its February sales but lower than their figures from January which was at 10.1%. The company has been posting good numbers as of late because their desktop sales have also put them on the top five list of NPD. They took a respectable 7.7% of the market in that respect.

This should not be any surprise, since Apple really has established itself in the notebook field. Will their upcoming new releases be enough for them to claim the top spot on the ranking? We will have to wait and see.
