A few months ago one of my favorite web services was sold by Marco Arment (its creator) to Betaworks. Since then Betaworks has been working hard on improving Instapaper and its apps. This latest iPad update is no exception.
The premise of the service is simple. You see an article you want to read later, send it to Instapaper. I've been sending stuff to Instapaper for several years now. You should give it a try if that sounds interesting. The web app is free and the iOS app is pretty inexpensive. It's also available for Android.
