I start medical school soon. I have a 2006 Core Duo Macbook that still serves me plenty well. The reasons why I don't want to bring it to class are 1) it's too heavy and 2) the battery doesn't last long enough. So I am considering an iPad for it's portability and long battery life for extensive note taking. But I've never used an iPad before and need advice on how current medical students are faring with their iPads. Which apps do you find most useful? Do you use a stylus? How productive are you with it? My other options are a Macbook Pro for it's long battery life, but it's not that much lighter than my current white Macbook. Or a Macbook Air, but 5 hours I don't think can last me a whole day. But I'd love to stick with the iPad if possible for it's price. Any insight provided will be greatly appreciated!
