I don't understand why strangers can't mind their own damn business. It seems everyone here who takes out their iPad in public has to deal with these nosy idiots.
I have used mine in public one time. Materials for a class were given to us as 30 separate files, no printed material, so I thought I'd save some paper and use my iPad instead. The iPad performed perfectly for this purpose. However, I ended up spending a lot of time dealing with busybodies who think it's OK to bother a total stranger and waste his time with idiotic questions. These people knew what an iPad was and were interested in the concept, but none of them had bothered to spend even one minute on the Apple website learning the basic info and they all thought it was OK to impose on me to bring them up to speed on the iPad's features.
I'm was too polite to tell them to leave me alone, but next time I don't think I'll be so accommodating and then I will be the one looking like the bad guy. "Elitist Apple jerkoff," they'll probably think.
