The units do the same thing the same way. Navigating the menu system is the only difference.
Using the buttons on the cross-touch version is the same as the NT version.
I did not want a touch screen and would not have bought an ONIX at all until the NT version came out.
I got the ONIX10 SI NT to run the 360 since it has a higher resolution display than the 1100 series.
Dedicated Down Imaging is nice too, but I rarely even turn that on.
