Re: Close but no cigar
The Nokia E7 had a great form factor: a really nice slide out landscape keyboard, which was very quick and comfortable for typing on. Even if you were using the phone in portrait mode, it quickly became almost an automatic reaction to turn, flip, slide, type, if you wanted to write anything more than a few words. And there was nothing stopping you from using the on-screen keyboard in either portrait or landscape mode if you wanted.
(Unfortunately, Nokia set fire to Symbian (and also MeeGo) before I could find out just what the longevity of the admittedly somewhat complicated hinge arrangement really was…)
