I use the stylus also, so the buttons could be smaller.
I tried out your 16x9 version and found a couple issues. My resolution is actually 1360x768, don't know if that is an issue.
"my weather" button is too small and so it does not display "my weather", but is blank instead.
The audio controls window has buttons outside the window, also when I click a music track, the window that lets you choose play track, play cd, etc is messed up.
I did get good transition between sage and xlobby when using the PPC, but what command do I use inside sage to get it to return to xlobby?
