Because switching over is not 'addressing bugs', it's like saying installing Android on it would address the bugs. Do you honestly think that (no matter how buggy Fremantle is), replacing it with a *FIRST* release of a whole new OS (on all layers, system, middleware and UI) will result in something LESS buggy ?

No. MeeGo does not ADD functionality to Maemo per se. It REPLACES Maemo. That means some functionality will be added, some functionality will be different, and some will be lost. At first a lot more will be lost than added, and then slowly, as the platform matures, things will get better, just like they did in the previous Maemo iterations. At that point the N900 will be way too old to be useful, HW-wise. Qt is good, but it's no miracle cure, the code will not write itself in an instant.
