I have not personally used the mach 3 2010 screen set. I did follow some of it's development on the Mach yahoo group/forums. If all you want is a clean uncluttered screenset with a good view of the toolpath preview window then it is a simple settings change to switch from the default screen set to the 2010 screen set. (I'm not in front of my router now so I can't give the exact setting)
Where you get into the extra setup is when you start using the auto zero features and other advanced macros that this screen set makes readily available.
I have heard many good things about this screenset and personally like the way it flows better than the default. It seems to be a lot closer to the AXIS interface for EMC2 which I'm familiar with.
For those wondering what we are talking about the screen set and additional info is available here:
