I use a desktop at home and want to get a small laptop or netbook for use of up to 4 hours. The spec doesn't have to be fancy - just enough to run Windows/Ubuntu, don't need massive disk storage, to be honest 80GB is more than enough, but 2GB ram would be useful for running multiple apps or having about ten windows open. I will probably be running of mains adaptor so battery life is also not a major factor. My concern is screen size - I have sensitive eyesight that means I suffer from eye strain quite quickly. I am concerned that a small screen, i.e. 10.1" as with many netbooks, is likely to lead to eyestrain after only a couple of hours. Can anyone comment on their own experiences along these lines?
