Surely a nice job: everything seems to run smooth (which is VERY important for an Amiga feeling).
But generally I'm very skeptic about the "touch interface" in general, especially for playing games, classics even more.
I won't feel good with such kind of controller...
I had a touch phone (ok, not the iPhone but a basic LG Cookie) and after few months I sold it, mainly because touch is fancy, but far from being comfortable in the long run, from what I expect from a phone (eg. one-hand-operation only, preciseness of operations).
Anyway it's a good job!
Merry compliments for 68k code ARM optimized!
