I had a Symbian UIQ phone years before the iPhone and it's remarkably similar in overall design. One big touch screen with no face buttons, rows of icons for launching apps, etc. All the pieces were really there. But the Symbian OS itself was terrible; I coded for it and it was a mess. It was quite functional, didn't really crash, but it seemed like it achieved that through sheer effort and will rather than good design.
