If you have access to the web, the first advantage which comes to my mind with a computer is a permanent giant and universal library.
Thus, with a successful Research roll, you can find data on any subject you want. Unless they are protected of course. But here, Computer Hacking (or one of its more realistic incarnation) can help.
Edit
Back to home and having at last access to my books, I would use the High-Tech rules for Libraries, here (see High-Tech, page 17-18). The GM would choose between "Small Collection" (-2 or worse to the Research roll) to "Fine Library" (+2 to the Research roll), depending on the subject of the research. For a research about a very detailed and precise topic, for instance, the Web doesn't really give a lot of answers; as said by Jason Taylor, it is more an Agora than a Library; so I would use "Small Collection". But for a more broaden subject like "Where are the good restaurants in that town?", the web is perfect and, then, I would use "Fine Library".
