I'm a heavy Fitaly user and find it extremely useful and fast. Since, I would like to see a version for the iPhone -or the new iPod for that matter, since it's a general purpose computer capable of running software- that could be used with the finger or why not? with a stylus. As a matter of fact I use a stylus with every touchpanel gadget which is located in my Lamy multipen.
Please consider this development.
