I read through this entire thread and became much more educated on many of the perceived or real problems people are having - this part I liked. Berating people for answering the original post question, no matter how they reply - not so much - especially from one labeled "Super Moderator". Its their opinion and they are entitled to it - let them voice it and if you don't like it DONT READ IT. Its kind of like people complaining about what's on TV when all they have to really do is CHANGE THE CHANNEL. Now, actually showing people the error of their ways and educating them how to get around what they feel is a problem is excellent, but it could be done with a bit more compassion couldn't it? Afterall, what we must remember first and foremost is we are not all at the same level of understanding - some of these posters only got their iPads a few days/months ago.
Now, for me, it is Flash and USB for the same reasons as already mentioned.
