I am looking for people who have actually used both and can say which they prefer. I am also considering Noteshelf and UPad. I mainly need to use it to write down and sketch out ideas. I do flow charts and some minor wire framing of websites and know both of these have shape support that should be helpful. I like the zoom to write feature. It looks like Note Taker HD's ink lag's behind the stylus from what I have seen of videos. Is this true? Notes Plus reviews talked a lot about crashes and losing data, anyone experience this? The only one I can try before I buy is UPad which I think the writing is fantastic, but there are no shapes. The zoom in and out is very slow, and there were some complaints about crashes losing data in the reviews. Once again, this is mostly for getting my ideas down on paper, not keeping up with a professor so I have no interest in paper and pen, i'm getting rid of that. Thanks for any thoughts!
