When it comes to entertainment, iPhone eats N900 / Maemo alive. But then again, Maemo 5 / N900 is so new that there's no way it could match the software portfolio of iPhone Appstore.

And I don't think it ever will, it's simply not as attracting as a development platform at the moment and I doubt it will reach that kind of popularity during it's lifespan.

Maemo 6 and the next device - who knows.

Some good games I play on iPod Touch:

Geodefence & Geodefence Swarm, Angry Birds, The Settlers, Rolando, Space Invaders: Infinity Gene.

The iPod has totally pushed PSP aside as a my primary portable gaming machine.
