I'm considering purchasing an iPad 2 to use on the go and also as a pdf reader and I have a couple of questions: 1) I'm a med student and as a result I have alot of very big PDFs. Is the iPad 2 powerful enough to comfortably display a 300mb, 1200+ page PDF containing numerous pictures, alot of text + a large number of tables/graphs? 2) How is the iPad for actually reading PDFs? I've had a play around on a Kindle before and was impressed by the eink. How does the LCD of the iPad compare? Note - I'm not going to be using the iPad outside in bright sunlight very much so the glare of an LCD will not be an issue. I also don't really tend to suffer from eyestrain from looking at a screen too long so that won't be an issue either. 3) If I do buy an iPad, I'm expecting it to be powerful enough (and reliable enough) to meet my PDF needs for at least 3 years. Is this realistic? Thanks!
