I agree with porcupine8 that in the context of this discussion, functional implies better, because you were responding to her categorizing an iPad as a tool. Tools are supposed to be functional, therefore when you said Android was more functional, I too interpreted that as meaning that Android is better. But you've since retracted the use of that word, so let's not argue this point further.
As for your insistence that tablets are just toys and not tools, well that's your OPINION. As you said, this is a discussion forum, so people have different opinions, and if they see a different opinion than theirs, they argue with you. There's nothing personal about that. I don't think porcupine8 is taking this discussion personally at all, but if you do, well, that again is your OPINION.
I do, however, agree with you about people who buy keyboard cases -- I too feel like saying "Just buy a laptop!" But this too is our OPINION. We may not see a point in keyboard cases, but apparently other people do, and while we may be puzzled by this and feel it's stupid -- well, other people are entitled to their opinions and preferences. *shrug*
Lastly, in my opinion, you are the only one making a big deal of your having "dared to" mention Android. I mean, again like you said, this is a discussion forum devoted to iPads, of course if you mention Android it's going to provoke a discussion. That's so predictable it's not daring, it's just boring. Well, that's MY OPINION.
