Apple has introduced an updated version of its low-end 21.5-inch iMac for educational institutions, using at dual-core Intel Core i3 processor and integrated graphics to offer pricing of $1099, $200 cheaper than the entry-level pricing for consumer models. The education-only iMac, which carries a model number of ME699LL/A, also includes just 4GB of RAM and a 500 GB hard drive, while the low-end consumer model doubles both of those figures.
