I'm writing this on a Fujitsu Siemens Amilo Li2727, that cost £249 about two months ago. It's fully featured, and other than it's running Windows Vista, I don't think I've ever bought any IT equipment in 22 years that has been such good value, or delivered as much bang-per-buck for the money. It's even less expensive than the last two PDAs I bought.
The point being, that while all these sub-notebooks are rather good... they are a bit expensive. I know they have fallen from thousands to hundreds, but the Acer Aspire One... that's the price point that they need to hit. The success of the eeeeeeeeeeeeeeeee PC was its price.
When will El Reg test the Acer? I've only read good things about it elsewhere.
