A few years back, I had to borrow someone's computer to fill out the UK passport form. It was full of extensions that only worked in the latest version of Adobe Acrobat - which wasn't available on Ubuntu (at the time). I couldn't even print the form and fill it by hand.
Yeah, it’s bad when governments depend on proprietary formats like that. It would be better if they would use a simple web app for entering the data, and then generate a PDF server-side. (Or even better perhaps, just let the whole application process live online.)
