I have found that most apps which are ipkg'ed for the 5x00 series models work just fine on the 6000, and even some apps for C series Zs.

I've noticed that most of those apps don't appear properly if you VNC into your Z (I'm using the beta for 6000). They're only about 1/2 screen height and are doubled left/right.

This can be fixed by tap+hold on the application icon and deselecting "Display with magnified screen" in the following dialog.

And the apps seem to start up more quickly, too. (Probably don't need to go thru the resizing functions).

Thought this might be useful for anyone who likes to VNC into their Z but found the miniturized, doubled viewing unusable (which it is).
