I will let the app update when i am above ground, but then i go underground for many hours and would like to read full articles .. teaser paragraphs are of no use to me
There is a way to make google reader fetch entire articles. Its and option or an addon or something. If you can figure that out, its just a matter of getting an app that syncs with google reader. BeyondPod does.
NewsRob is free and will download as much or as little content as you want for offline viewing. Up to 1000 articles.
It only syncs with google reader though.
That why I like NewsRoom it's stand alone app and doesn't require another service to work. In fact from within the program you can type in the URL of a page and it will scan the page and attempt to locate the RSS feed and bring in the content.
I don't use a lot of apps but I really enjoy this one.
It will aggregate all your feeds, and I've seen the option to save all images to sd card. It is updated often and has a great widget, and it supports google reader
