Apple has significantly improved its affordable Mac minis, doubling installed memory and adding Bluetooth and Wi-Fi as standard to some models.

The two-model Mac mini family now counts three members. All ship with 512MB of memory, with wireless access in the faster models.

However, kicking the industry trend toward lowering prices, Apple has actually raised them: Mac minis now start at £359 for the 1.25GHz model, up from the previous £339 entry-level price.

Both the 1.42GHz Mac mini models feature built-in AirPort Extreme and Bluetooth with prices starting at £429.

The top-of-the-range model also offers a 1.42GHz processor and carries a SuperDrive. It costs £499. The previous highest-priced Mac mini cost £399.

David Moody, Apple's vice president of worldwide product marketing, described the new models as, "delivering an even greater value in an innovative compact design".

Connectivity options include: one FireWire 400 and two USB 2.0 ports; a DVI that also supports VGA so customers can easily connect to a variety of LCDs or CRT displays and built-in 10/100 BASE-T Ethernet. They also offer a built-in speaker and headphone/line out.

All three models ship with ATI Radeon 9200 graphics processors with 32MB of dedicated video memory.

Like all new Macs, these Mac OS X 10.4 "Tiger" powered computers ship with iLife 05. The accompanying software bundle that ships with these machines includes: Nanosaur 2.0 and MarbleBlast Gold.
