I do not own an ipad, but am considering it as I've heard so many people say "It's the best thing I ever owned". I want to do three main things, and I need to know "can I do this?", and "what is the best free or paid app for it?".
1) While I'm in the library, plug in a USB drive that contains my 10,000 excel files and open them so I can see what data I need to research that day. Laptop is possible, but very bulky and much less convenient. What I want to do is read only.
2) While I'm talking to a client in a sales meeting, draw out a sketch a la white board, and have an app that converts that sketch (however roughly) to a Visio.
3) While I'm teaching a kid math, write on the ipad like it's paper (multiple pages even cuz I write large...), save the graphics and notes along with the audio of our session, and then a) e-mail them to the kid later, and b) save them (converting my scrawl into math type would be primo) so I can collect them one day into a "this is how I teach these subjects in math" book.
Maybe this is too advanced, but I need to know if for $600 I can do these things please.
Thanks very much for the help!
