Sounds like an interesting development.

I assume this device has bluetooth which means you should be able to attach a bluetooth keyboard to it?
If not maybe developers can hack the source and make it possible?

What I like about my N900 is that it is the "most standard" installation of Linux compared to other mobile devices.

Android is "linux" purely by use of the kernel but everything else is "Google-ised" - e.g. their own special VM it's Java but not quite and their own glib library which means porting existing linux software is non_trivial.

At least with maemo porting linux software is considerably easier due to the use of standard components.
