Apple has updated its iMac and Mac mini desktop lines, including faster processors and twice the memory for all iMacs.
The entire iMac line comes with faster Intel Core 2 Duo processors running at up to 3.06 GHz, the latest graphics technology, double the memory and up to one terabyte of storage.
Delivering up to five times better graphics performance, the updated Mac mini now features the same Nvidia GeForce 9400M integrated graphics introduced with the aluminium unibody MacBook family.
Apple says the Mac mini is the world's most energy efficient desktop, drawing less than 13watts of power when idle.
The iMac line starts with the 20inch iMac at £949 including VAT, equipped with a 2.66GHz Intel Core 2 Duo processor, 2GB of 1066MHz DDR3 memory, a 320GB Serial ATA hard drive and NVIDIA GeForce 9400M integrated graphics.
The 24inch iMac features a 1920-by-1200 pixel widescreen display that offers 30% more screen real estate than the 20-inch model, and starts at £1,199 including VAT.
The 24inch iMac includes up to a 3.06GHz Intel Core 2 Duo processor, 4GB of 1066MHz DDR3 memory, and a 640GB or 1TB Serial ATA hard drive.
Starting at £499 including VAT, the Mac mini is a tiny desktop measuring only 6.5 by 6.5 by 2inches. Available in two models, Mac mini features a 2GHz Intel Core 2 Duo processor, up to 4GB of DDR3 1066MHz memory, up to 320GB Serial ATA hard drive, five USB 2.0 ports, FireWire 800 and a SuperDrive.
Using less than 13watts of power when idle - up to ten times less power than a typical desktop PC - the new Mac mini is the most energy efficient desktop in the world, said Apple.
The new iMac and Mac mini lines are now shipping and available through the Apple Store, Apple's retail stores and Apple Authorised Resellers.
