To think they used to say that one couldn't do real work or create content on the iPad... Enter Weebly for iPad, a native application by the popular web-hosting service which allows users to create websites in minutes by dragging and dropping various elements in its web interface.
Although it's been available on iOS since May 2012, Weebly was iPhone-only until todays update which has brought out native iPad interface with full editing capabilities, unlike the iPhone and iPod touch version.
Weebly is available free of charge in the App Store.
