I have only two major concerns of using ipad2 (or ipad3 or ipad1 if it proves unworkable on ipad2)...
1. privacy & security: I don't just mean low level privacy, I mean that as an investigate journalist working on sensitive subjects, I need to be immune form well-funded organizations reading my content or tracking my movements - whether it's in China, USA, Russia etc. So, I am suspicious of 3G, even its non-3G subscription service as it seems to require location trackability to do such simple things as reading maps and customizing them (seems odd to me, what is the relevance of where *I* am when I just want to know the layout of streets in London or Moscow?) I have purchased my ipad with cash, registered it to 'John Doe' and presumably buying all apps with anonymous gift cards.
2. international utility: My work and hobbies take me all over the world. I can't be tied down to limitations of national borders or an app working in nation A but not in nation B.
All the entertainment, business and news apps are unimportant.
Is anyone else on this forum working with the same goals and finding solutions?
