Mine came yesterday and I've had about an hour to play with it. I had an Explorer II way back when and am mostly familiar with the T2 and F75 platform. So this is a totally new beast to me...seems pretty straight forward in the menus though...and very tweakable. Wasn't real impressed with factory programs in my test plot but scoured the forum for some programs and saw this TTF mode being popular. So I opened the whole disc box and put it in TTF mode. Seems to make it behave similar to the T2 in 2+ mode that I use a lot. Got a learning curve to get across but think it wont be bad.
