So, the little, new Acer Aspire One will do the trick. I was able to pick it up when visiting friends in the US. This means I got hold of the straight English keyboard rather the silly bilingual edition which are the only type available in Canada.
I spent a great part of the day with it, and I can read text on a 8.9" screen. I can type on the keyboard that's not standard size. I certainly will be able to carry it around as it weighs less than one kilogram.
