Me too! They probably will in the future. It is strange that the Nook apps for iOS and Android seem to have more features than the nookcolor stock reader. I really got spoiled to the two column landscape when I had my Sony PRS-900 and later the PRS-950. BTW, I didn't show it, but the Nook iOS app has the two column landscape feature. I assume the Nook Android app does too.
Currently: Kindle Touch, iPhone 5, and iPad 3.
