I hope that I can get some advice from people who have actually used the full sized iPad. I am an Android user, a happy android user. I have a galaxy nexus and a nexus 7 and I really like both devices. In general for me personally iOS has always seemed very limiting (not trying to bash anyone else's choice). BUT... I am a grad student and I have to read scientific articles as pdfs all the time and I was thinking that it would be really nice if this were an activity I could do on my tablet except the nexus 7 is not ideal for this (too small, aspect ratio all wrong) and I use Papers by mekentosj to organize my articles on my mac and they have an iPad app but I don't think there is any chance they will ever develop for android. Nor do I know of a pdf organizing app that will work as well for android. I also wouldn't mind having access to better games that didn't try to sell you on the freemium model. Is this any better on iOS? It is awful on Android. TL;DR: Main question: is an iPad as good as it sounds at reading pdf articles, particularly research articles that come usually in two columns with lots of figures in between (so reflowing text is not an option). & for anyone who actively uses Android and likes it, does iOS get frustrating to the point that I would regret buying the iPad. I don't really care about widgets but I am concerned about the lack of access to the file system. I hope to make it clear I'm not trying to criticize any OS. I just wanted a little input to help me make a decision on what will work for me. Thanks!
