The very rare and elusive Harvey Norman "helpful salesman" saw i was using an N1 while i was shopping for TV's and recommended i look at the app "LCD Density" He showed me his HD2 with it and it looked worth the effort. 

I don't know specifics but it's added quite a bit of real estate to play with which is nice. Icons are all a little smaller though so if you have trouble reading small fonts it's not for you. 

Check it out, i'm finding it helpful.
