it certainly used to be the case that the flavour of linux these things shipped with was crap. I had a 701, and xandros was rubbish. My dad's HP Mini had opensuse, and that was similarly crap. I wiped it and installed debian, and did the same for him. So researching the OS might still be as important as the actaul machine - certainly a more mainstream linux might be a good choice from the point of view of future support (I believe the Dell's come with ubuntu, not sure about the others).
That said, with linux, viruses are much less of an issue, which can be a real boon on a computer used mainly for browsing.
