The technology itself works quite well. I did not like feel of the pen. The roller was approximately bic quality which is unacceptable for a $200 pen. My pen died after a couple years of virtually no use. It would probably require a redesign of the pen, but I find I prefer gel pens nowadays and wish there was a gel pen insert.

If you REALLY REALLY need to take notes during meetings, its the best thing ever. I find in most meetings however, there's probably one or two facts I really need to know. I decided that instead of taking notes I would just stop caring about meetings. I enter those one or two facts into evernote on my phone and I'm done with.

They are awesome, if you ofter review hand written notes then get one, and if you work with people who don't mind you recording conversations (such as requirements gathering sessions) they are really useful.

Pretty much use mine daily

I use mine to create annotated recordings of lectures. It works quite well for that purpose. Clicking on my notes skips the recording directly to the relevant part of the lecture.
