In contrast to their ceaseless quest for raw computing speed (typically now 3GHz) computer manufacturers have recently adopted multiple slower CPUs, with two ("duo") and even four ("quad") microprocessors under the PC lid.

Dual Picaxes! The left Picaxe is the "sensor" while the right Picase is the "doer". Each must be programmed individually.

Doubled-up chips such as as Intel’s popular "Core Duo" offer paired microprocessors working at slower speeds (typically 1.5GHz), resulting in lower overall system energy consumption and reduced waste heat.

Given the trend towards ever slimmer and lighter computers, these benefits are especially welcomed, since laptop battery life can be greatly enhanced, weight trimmed and noisy cooling fans reduced in size or even dispensed with altogether.

Paired computing hardware may be akin to a twin engine aircraft – two smaller engines providing more performance than one larger engine – but the concept has even lead to Microsoft’s imaginative MultiPoint PC mouse software, potentially offering great appeal in developing world education.

Multiple USB mice may seem like a video game controller octopus but in resource-constrained countries with limited classroom computers, the ability to connect many mice (each with their own coloured screen icon) may allow valuable student collaboration, enhanced learning and simulation. Naturally, programs will need to be specially written to exploit the Multipoint’s potential.
