Apple has launched Apple Store Pro card, a loyalty-card discount scheme for US Mac users,

The 10 per cent discount scheme is designed to generate sales at Apple's retail outlets. Apple says its card is a "passport to a world of benefits and privileges designed exclusively for the professional Mac user".

Among other benefits, the card offers holders free transfer by Apple shop staff of all G4 files to new Power Mac G5 systems.

A cardholder can also book to come in to buy discounted software, and get free installation of any software purchased in-store. Cardholders also get a guaranteed next-day appointment with Mac Genius staff.

Apple hasn't yet informed its US users how they go about acquiring the card.
