Hello Mark. We are currently piloting the FSA 3.0 app on Microsoft Surfaces with positive feedback. I'm not sure about the iPad interface, but I do think that it looks a lot like the MFL interface, with some minor UI enhancements. There is a new version of the FSA app 3.02 which is coming out tomorrow, 10.6 which has a few bug fixes included.
The best part about the FSA app is that you can capture signature on any touch-enabled device and also on regular laptops using the trackpad. This was previously not possible using the MFL. If you end up piloting on a Surface, please share your experience with us!
