I am studying a MSc in project management, the course is research based and i am a slow typer and a generally lazy person so anything that can give me more time to bum around rather than typing 20,000 word dissertations interested me greatly. Reading the reviews it was a difficult decision to part with the cash for the pen as everyone seemed to have different experiences with it. I am so glad i purchased the great little pen, for me it is pretty much 100% accurate, it scans straight into word (for mac) underlining in red grammerlicious errors so its easy to spot anything that confused it. it is great as a study aid as it forces you to read the text during scanning, and again checking the document, rather than concentrating on typing. it is just sooooo much faster, 1-2 seconds a line straight into word. i use a mac, not sure if that makes a difference with the software but in reviews mac people seem to have a much higher success rate. my advice, buy it, it will change the way u work and study for the better, if you're hamfisted and cant use just return it and get your money back.
