Instapaper Blog: Preview: Instapaper on iPad
While I could have taken the conservative option and waited until a month or two after the iPad’s release before launching Instapaper for it, an iPad without native Instapaper Pro is not a device I want to own.
Instapaper is probably the single iPhone app I cannot live without at the moment. So it's nice to know I have one less reason to try not to buy an iPad..
