Apple introduced a wireless keyboard and mouse at Apple Expo Paris.

The products are based on Bluetooth, and are the first ever products to feature Adaptive Frequency Hopping (AHF) – reducing interference between Bluetooth devices and other wireless networks and devices, claims Apple.

The company also says the input devices provide reliable performance “at up to 30 feet and offer secure 128-bit, over-the-air encryption”.

The keyboard and mouse complement the updated PowerBook line that now features Bluetooth support as standard.

Jobs told his keynote audience: "These will be great for offices and classrooms."

Phil Schiller, Apple's senior vice president of Worldwide product marketing, said: "The Bluetooth-based Apple wireless keyboard and mouse are an ideal complement to our new PowerBooks, and provide our desktop customers with an elegant way to eliminate cable clutter."

The one-button mouse features an "easy-to-use ambidextrous design", and an optical tracking engine “provides responsive and accurate cursor movement on almost any surface", according to Apple.

The wireless keyboard features 16 function keys, full numeric keypad, inverted-T, audio control and the ability to eject optical media.

Both products switch to low-power modes during inactivity and can be turned of when not in use.

The mouse requires two AA batteries, which Apple claims provide up to three months of use. The keyboard requires four AA batteries, for up to nine months of use, says Apple. The Bluetooth peripherals run with Mac OS X 10.2.6 or later, and systems that feature a built-in Bluetooth adaptor or an external D-Link USB Bluetooth adaptor.

Apple says the products will be available in two weeks on the Apple Store and at Apple Authorized Resellers, priced at £59 each.
