Itouch as an input device for forms

Hello
I was wondering if I set up a .pdf form, would the itouch be a good input device? The scenario is for new patients to our clinic to have a way to fill out the forms and then upload them to the database.
It seems the perfect size but I am expecting that it would need to be hacked and I am not sure how stable that would be over time
Would the Itouch accept one of those spiffy operating systems and office suites for usb drives that would make it more of a computer? (Sorry that just does not seem the right way to say it but you get the idea)
Would an Iphone make the cut if the Itouch is not the right equipment?
Thanks in advance for your help
I really want to keep it as simple as possible and it seems that
Tablet/notebooks seem frought with more battery, weight and intimidation, as well as potential operating complications than I want the office people and patients to have to endure.

html vs pdf or word

Thanks for the advice.

I guess I saw doing it in word and transfering to pdf or just in pdf as more of a word processing thing that I had some familiarity and was capable also of inputting the data into a spreadsheet but coding html seems daunting. Are there any cheap software packages that would code html like that (without a steep learning curve)?
