are the best then you aren't getting a true answer to the question. From what I've heard Acer does rank up their with the others. I think it's better to choose a laptop based on your need rather then on others preferences.
My girlfriend needs a laptop. For her light PC use and constant travel I have convinced her she is best off with an Netbook.
Her Netbook would have to be AT LEAST 10" so it would be comfortable, both to type on and to look at.
So which of the 10" models available (not counting ACER) is best?
The current favourite is the Samsung NC10
