Apple iMac
Show price: TBA* (usual price: from $1,788 for 21.5-inch model)
Booths: 8338, Ballroom 2, Level 3 foyer

Touted as the ultimate AIO desktop, the iMac (below) now puts everything you need - display, processor, graphics, hard drive, optical drive and more - in a simple but sleek aluminium enclosure.

Generously-sized LED-backlit screens - from 21.5 inches to 27 inches - make viewing high-definition videos a joy.

Fast dual-core Intel chips that start at 3.06GHz mean the machine will not stint on performance.

A wireless keyboard and a Multi-Touch Magic Mouse keep things clutter-free. The 21.5-inch iMac starts at $1,788, while the 27-inch model starts at $2,588.

Promotion: Apple retailer EpiCentre is offering the AppleCare Protection Plan for as low as $99, along with other freebies, when you purchase a Mac at the IT Show.

Inside the thin frame, an AMD Athlon64 X2 6850e dual-core chip is teamed up with 2GB of memory, a Nvidia GeForce G210 graphics card with 512MB dedicated graphics memory and a 320GB hard disk. Good enough for everyday computing.

The budget system comes with a one-year warranty and runs Windows 7 Home Premium.

Besides having the Windows 7 OS, it comes bundled with fun applications. These include CamSuite software for enhanced facial tracking and image effects using the desktop's built-in webcam. Lenovo also promises an optimised bootup and shutdown with this PC which is aimed at home users.
