This new beta has changed my DR800 pretty good to nearly perfect. An inbuilt dictionary would be awesome as I study philosophy and they love to use complex language. Highlighting would also be good, well better than underlining. I will be interested to see the finished patch and how it handles zoom. A little more robustness would be good as has been commented on.
Oh and while you are at it, please put in full web browsing and hand writing recognition. OK? Good thanks.
Also, great to see how involved iRex is in making this product highly functional. I'm glad I spent the extra $$ on this over their competitors.
