The NVIDIA GeForce 9400M graphics chipset used a portion of main memory as VRAM. Though reported as a 256 MB graphics system, the chipset actually used up to 272 MB of RAM.
Introduced in April 2009 and sold only to education markets, the iMac (Mid 2009) was a cost-reduced version of the 20-inch iMac (Early 2009), with a slower processor, less RAM and hard disk, and (notably) no Bluetooth. It shipped in a single configuration, with a 2.0 GHz dual-core processor, 1 GB of RAM, and a 160 GB hard disk, for $899. Built-to-order options included up to 4 GB of RAM and a 320 GB hard disk. In March 2010, the processor was upgraded to 2.6 GHz. In March 2011, the standard RAM was doubled to 2 GB. It was replaced in August 2011 by the iMac (Late 2011).
