【討論】T600 vs. T615

First, let me say hi!  This is WPK from the U.S.A. and this is my first post.  Nice site here.
  
I have a question about the Japanese CLIE T600:
  
When a Japanese T600 is "localized", or somehow re-flashed with an Enlgish ROM, how would the silkscreen function since the Japanese version has extra "buttons" there and thus a smaller Graffiti area.
  
P.S. Is there a way to purchase the T600 from overseas?
