Looking for testimonials for people who have actually used one for an extended period. I'm looking to get either a new iPad or iPad mini. I'll mostly be using it for reading on the train and would prefer a smaller size for that, but I'd also like the option of using it to take notes at conferences and to carry as a bare-bones travel laptop. Is the mini realistically too small to do work on? Should I just suck it up and get the full-size version?
