We've been doing this for years with our various tablets, and it's one reason I bought the edge. But yesterday I needed to sign and return tax forms to our accountant, and this is a situation where the watermark simply isn't appropriate. (I bumped the pdf exporting thread with the same comment.) We've used the little N810 internet tablet to fill out/sign forms related to purchasing and selling houses and other legal documents, and you really can't do that with the watermark. I had to resort to the N810 yesterday, though I was excited to try the edge for this purpose yesterday for the first time. (That's when we noticed the watermark.) For my own documents, no big deal. For the forms we're always filling out, though, it is.
