The Acer Aspire 5710Z has gone on sale in Singapore pre-loaded with Ubuntu Linux instead of Windows. Ubuntu is currently one of the world's most popular and easiest-to-use Linux distributions. But a spokesperson for Acer told ZDNet.co.uk on Tuesday that the company - one of the world's top laptop manufacturers - had 'no plans' to sell any Linux-based systems in the UK. "[Acer models] with Ubuntu pre-loaded are available at the factory level. However, there is no demand for it in the UK. Therefore, those configurations are not an option [for UK customers] at the moment," said the spokesperson.
