I see the front-facing camera here in the bottom right next to the Nokia logo.
In fact, I think I can make out the light sensor too (and maybe the buttons ?). It seems that they swapped the order of cam and sensor, as have been suggested before, so cam on top.
With "click outside dialog to close", you don't need one, really. That's at least my impression when trying out the concept on a ESC-less touchscreen device.
I don't think you can say Android is more stable, because you can argue maemo is more of a standard distribution than Android. Maemo benefits a lot from upstream commits.
I just meant Android 1.5 Final versus Maemo 5 Beta 2. Things will be different obviously with Maemo 5 Final and Android 2.0 Final.
