I think it's normal that people tend to go bigger.
I mean we want always the bigger car, tv, etc
My brother has the 7" Eee and i find it a little small for normal work and surf the web. On the other hand he finds it very good to surf the web.
So i think that this is more of a personal choice.
For me i think that 10" is the minimum for a netbook to be great at work and surfing the web, it has the right balance between price and features offered.
