If the leaked N8 (S^3, N87 12MP) and N98 (S60v5, polished N97) are real, then Apple doesn't stand a chance. While high-end phones don't account for a significant share, they are the ones that give a company good reputation - which is what Nokia needs right now badly (in the Symbian high-end segment, which isn't the one that accounts for the increase).

The N900 could sell more only if advertising, support and of course supply would be there. Obviously Nokia believes that the S60v5 UI is more "casual-friendly" than Maemo 5's counterpart.
