Dennis @ PerfectForms
Our next release V 2.0 will include limited HTML5 capabilities. Basically it will allow users to respond (approve/deny) to email notifications with a mobile device. PerfectForms requires Flash. If you are designing forms for use on mobile devices that run Flash (I use a Xoom), keep the restrictions of a tablet in mind. Put less on each page and make the check-boxes bigger so that they are easier to use with a touch screen. On a tablet, the user can only scroll through a screen with the scroll bars, and not by sliding their finger down the page.
We plan to have full HTML5 functionality before the end of the year. However even without the Flash requirement, you will still have to design forms for mobile use differently to accomodate for screen size.
