I don't think copyright infringement is the issue. Making a copy to view offline is always legal (well, fair use clauses sort-of make it mostly legal) and you are doing that with a web browser anyway, with cached pages, and cacheing proxies and similar devices also perform a similar function. The protections afforded by copyright all pertain to public reproduction and dissemination. The WSJ point about restricting the number of free article views made in another reply is similarly nothing to do with copyright. This is more of a contract issue, and anyway, if I can view only N articles for free, I can only save those N, so it is really moot.
