Well, it was more like a "just in case" clause, but if you really insist, it would have to compensate the lack of the qwerty at least by having full MeeGo (with later upgrades), Android compatibility (Alien Dalvik), VoIP and chat support integrated (like N900), good front-facing camera (unlike N900) etc... and of course, a smoking hot software kbd (although I have absolutely no idea what that means).
