Notebook with wifi and intergrated mobile internet

[jamesuk28]

Hi Can anybody recommend a notebook that has wireless capability, is small and light, costs less than a grand new, and crucially will allow internet surfing via a sim card or mobile network when out of range of a wireless hotspot.

I know this is possible via blue tooth, but would like it intergrated in the notebook.

I know there is another post about the following, I want to be able to log into my websites and email while abroad in Italy, am I going to get shafted on roaming costs too?
