I'm a fan of keeping everything simple and practical, so I have the kobo app on my iPad. That way I have my entire e-reader library at my finger tips, plus all of my other apps that I use daily, including my outlook account. Sometimes reading on the train is all I want to do, but other times going through my emails or working on an article is time better spent.
Using my iPad makes the most sense because it condenses all of my needs into one device. Now my problem is that if I ever lose it for some reason, I will no longer know how to survive.
