Hi I know this was posted before, but I'm concerned about the specifics here. I've done 1 year of med school, and I'm overwhelmed by the massive amounts of books, powerpoints, and paper that I have to deal with. I would like to be able to constantly read from the books and powerpoints, so I'm considering an iPad because my macbook 13" isn't serving that purpose very well. [portability and screen angle are a pain + it lags with chm files] Also, I'm still unsure if iPad2 can handle ebooks properly. For those of who you read CHMs/PDFs on iPad2, is it good enough? Does the glare cause a problem? Does it lag? Shows malformed text or images? I'm planning to read 3 to 5 hours a day from it, if not more. If reading from an iPad isn't any more comfortable than reading from a macbook, then it's not worth it. Oh, and how's the pptx file support? I was also wondering if it's worth it to get an iPad 2 by the end of this month or wait for iPad 3. It's quite confusing because I've never used an iPad/iPhone before. What do you think?
