I'm going to order a iMac in the next few days and will be customizing the order to have a wireless keyboard and mouse. Will this affect the delivery time and how long does it usually take for a iMac to get delivered? I am in the UK and will be ordering online through Apple.co.uk. Please tell me how long it took you to get your iMac. I've heard the delivery is quite quick in some cases but in others it can take as long as 3 weeks!
