"In fact, it looks and feels very similar to the keyboard fitted to the original Acer Aspire One, which was fine on a machine released two years ago and costing £200 but the game has moved on."
It has? I guess I need to try out an N140 keyboard then. I remember the Aspire One getting plaudits for its great keyboard on release, and I've always been very happy with mine. It's certainly better than that chiclet-style rubbish that seems so popular these days.
As for Sony's netbook, it just looks like more of the same to me. I've yet to see a model from any manufacturer that convinces me I need to spend £300 on a machine that's essentially the same as the one I spent £200 a couple of years ago.
