I'm a Biochemistry major looking to buy an iPad. being a biochem major i take lot's of notes (emphasis on lots) which include both in depth notes and organic chem structures. I'm wondering if there's an efficient iPad app that can let you handwrite notes and draw structures and let you sync them to your computer via PDF files or otherwise. Is there one that can do that and has handwriting recognition? Thanks much for the help. *update* I found a really cool app but still timid. Any good reviews on PenUltimate???
