Add Instapaper for Chrome to the list of Chrome web apps that aren't just bookmarks. This unofficial webapp adds offline article syncing, extended pagination options and saving of where you left off in an article to the popular read-later service.
Once you've installed Instapaper for Chrome and see it on your new tab page, you can right-click or click the wrench icon when hovering over it to get at its options and enable offline syncing. There are other options that are sometimes available, as the developer works through bug issues, but the offline sync is what really makes it worth installing this web app. Head to your Instapaper account page, and you'll see a new link for Offline Sync in the upper-right corner. Hit that, and the webapp will start grabbing articles for offline reading.
It's a bit beta, as you might have to refresh the page occasionally when Instapaper for Chrome hits some kind of limit. Still, it's really convenient to know you have access to all those articles you didn't have time to read, when you finally have time to read them — i.e. when you're totally disconnected. It's a free download for Chrome browsers only.
