The Acer Aspire One runs a little warm, and a small internal fan vents through the case bottom, thankfully very quietly. Unlike other Atomic-powered laptops, there's no provision to step-up the processor, but battery-saving settings are found in the KPowersave interface.
While this initial sample runs Linux with SSD storage, a follow-up Acer Aspire One will feature Windows XP and a 80GB hard disk - but expect battery life to tumble from the 3 hours 12 mins we acheived with this model. Also on the cards is a 3G or WiMax module. For the UK, expect to see the former in HSDPA form before long.
