Electronic pen to mark up PDFs

Hi all,

I am a technical writer and I'm looking at how to make it quicker for engineers to mark up manuals with their edits or updates. Currently we have some engineers using the comment/highlight features that Adobe has in their editing tools, which work well, but can be a bit time consuming for some engineers. And we have other engineers, particularly with big 100+ manuals, that like to print off the document for ease of reading and then mark it with pen.... and then re-scan it. Definitely time consuming but understandable why they might prefer it in long docs.

So I am looking at tablets (iPads) and electronic pens as a possible solution. Has anyone any experience of using this type of solution?

Ideally I would like an electronic pen that works with a tablet and would also accurately convert the handwriting to text. Does it exist!!?

Love to hear your opinions,

Thanks
