I had an iPad for a few months a couple of years ago, and got rid of it mostly because of the experience of editing text with a hardware keyboard - navigating and selecting text in long documents was simply a horrendous experience. My recollection is that navigating or selecting by paragraph simply didn't work, and navigating by line wasn't much better due to the inconsistent placement of the VoiceOver focus as you moved between lines.
However, I find myself tempted to give the iPad another chance. What would probably tip me over the edge, would be news that editing text with a hardware keyboard has improved during my time away.
So, it would be great to hear the experiences of those of you who do regularly use a hardware keyboard with your iPad. Are you able to reliably navigate and select text when editing long documents in apps such as Drafts, IA Writer, and 1Writer?
