The cheapest iMac you can purchase today costs $1,099. However, a glitch saw an $999 iMac appear on the Apple Store yesterday, but it's a model from 2006.

As Cult of Mac reports, the listing was spotted by Twitter user @DylanMcD8. You can see his tweet showing the iMac listing below, which cost $1,099, but those are Canadian dollars. On the US store the same model appeared for $999.

The 2006 iMac was a 17-inch all-in-one complete with a 1.83GHz Core 2 Duo processor, 512MB of RAM, and a 160GB hard drive. It's definitely not worth $999 today and clearly the listing is a mistake. It has since disappeared, with a "technical issue" being put forward as the reason.

News of the listing spread quickly after Dylan's tweet and another Twitter user named Joe Jonas decided to go through with the purchase. As his tweet confirms, Apple sent him a cancellation email 10 minutes later. It's likely people trying to order the model alerted Apple to the mistake.

Spending $1,099 on an up-to-date iMac gets you a much more capable machine today. The base model ships with a 21.5-inch display, 2.3GHz dual-core Core i5 processor, 8GB of memory, and a 1TB hard drive. Even so, that's not great value considering Apple is still using Intel's 7th-gen Core chips and upgrading to an SSD adds $200 to the price.
