2 Reasons (for me at least) for an N900 with Android:

* Decent Offline Navigation is something Maemo is lacking

* A good display is something all the other cheap androids are lacking.

That said I would prefer a decent offline Navigation with Maemo over anything else But i guess this is even more unlikely than a stable Android on N900

Besides those issues: I have a quite good experience with the Nemus Launcher on 2.3.4 and N900. Compared to Go-Launcher it was a lot faster and more stable (Tested with 1150 MHz).
