Apple will hold its annual iPod and media centric event for the week of Labor Day, scheduling the keynote for Wednesday, Sept. 9.

Expected to be a part of the event are “Cocktail” Apple’s full-length album download bundle with extras, and a new iPod touch and iPod nano, both sporting cameras, to be released together with a new version of iTunes, possibly with support for Blu-ray discs and social media integration.

A new study by Retrevo, an electronics product review search service, suggests students prefer low-cost netbooks over Apple’s MacBook, but some believe the Mac-maker’s long-rumored tablet could take a large portion of low-end laptop sales.

The breakthrough 10-inch tablet device with which Apple hopes to attack the netbook market, however, will probably launch no earlier than the first calendar quarter of next year, which runs January through March.
