I'm planning on getting an iMac with a wireless keyboard and mouse.That's going to cost me £40 ontop of the iMac it's self. Now this is were I'm confused, the replacement wireless sets cost £80 and the wired set cost £55 (when you buy them normally). So I'm paying £40 more, for £25 more worth of stuff. Is this correct? I though that the iMac had an Airport card by default so it can't go towards that. Are we just being ripped off?
