EasyWriter Pro - I was surprised that Apple did not add a landscape keyboard mode in its latest OS update. It's such an obvious omission I wonder just what they were thinking. I waited for the recent OS, hoping beyond hope for landscape typing, even though I had already heard rumors of the features the update would include.
I find entering text in portrait mode impossibly difficult because my thumbs are about the same size as Nathan's hotdogs. What happens way too often is that when I try to enter text, I make so many mistakes that not even the app's predictive mode does me much good.
Finally, I decided to bag it and get a landscape text writer that would make my life easier. The App Store has four or five of these apps and I settled on Sax Software's EasyWriter Pro because it has an editable list of ready-made snippets of text so I don't need to enter text to reschedule meetings, let someone know you're stuck in traffic and the like. That's less typing for people like me who have sausage-size digits. It would be great if it had a spell checker like Michael Schneider's TouchType, but that app has other limitations.
You can compile a list of favorite contacts and one tap gets you started on creating an email. When you're done typing, tap the Send to email icon and you'll go into iPhone's native email app where you can actually send the message. It's not an ideal solution, but it's the best these apps can do at the moment.
EasyWriter Pro is $0.99. There's a free non-Pro version that does not have the ready-made reply capability or the one-tap contact feature. The "lite" version is the most popular productivity app at the moment, but I think the buck is worth the extras.
