UPDATED: Apple Store down – new iMacs debut?

 Apple’s online retail store in the US and the UK is down, as anticipation climbs the company plans to introduce new model iMacs this week.

Introduction of the new Macs was anticipated to take place tomorrow, but Apple may have bought this forward for reasons of its own. Equally, Apple may simply be indulging in site maintenance of its retail store while the US sleeps. We’ll know more later.

EDIT TO ADD: The new iMacs are visible now on the Apple Store. They comprise four models in total, with either 20-inch or 24-inch screens, with a 2.4GHz processor at the bottom end, topping out with 3.06GHz processor at the top.

Prices appear about the same as before. More information follows.
