Too much machine for most people Computer boffins will long debate Apple Computer's claim that the new Power Mac G5 is the world's fastest desktop computer, but designers will be in no doubt that it is the most beautiful. Rarely has a computer been so well put together. You can almost see through the machine because of the ventilation holes at each end. Nine fans keep the monster cool and if you open it up and take off the plastic device that helps guide the air, the machine eventually will shut itself off. The latest Power Mac responded with considerable speed, both at boot time and when launching applications. A quick test of Quake showed the machine to be extremely fast at handling the graphics speed needed for the game. At 17.8kg, the G5 is a lot heavier than previous Macintosh desktops. It is also bigger. Of course, the Mac has just over 3 per cent of the market and, yes, you pay an Apple 'design tax', but you really do get what you pay for. You can go out and get a Sam Shui Po special for half the price - but it cannot compare.
