Apple has introduced a new rebate offer, called Music On.

The offer involves a £70 rebate to customers purchasing – together with an iPod – certain iMacs, iBooks, PowerBook G4s, Power Mac G4s or eMacs. It runs until June 30.

Customers can choose between the 5GB or 10GB iPod. The rebate is available from the Apple Store and Apple resellers. The iPod and qualifying Mac must be purchased simultaneously and appear on the same invoice in order to qualify for the rebate.

Customers can download the PDF mail-in coupon.

In related news, Apple UK and its preferred ISP Demon Internet have joined forces to offer £90 to customers buying a Mac and subscribing to Demon's ADSL service before June 30.

Those qualifying receive a £90 voucher to spend on any product available from the Apple Store.

The deal extends to Apple's small business customers and to customers at Apple's Store for Education.
