You're voicing a strong opinion, 'hate', on the entire range of products of a company whilst admitting you have little experience of using them. Some of these products are very complex ( OSX ) and take time to learn even if you're familiar with other similar products ( OSs ).
I find some of their consumer product frustrating also. The same things that annoy me about the iPad make it perfect to be my mothers first 'computer'.
I find their professional product, once learned, ( Mac Pro, OSX ) to increase my efficiency over all tested alternatives. ( tbh. I've only used BeOS a little )
The FAA didn't chose this, the airline asked them to look into the 'look into' the iPad, and no one has paid them to 'look into' any other device. You're very welcome to.
Please look at where your post could be considered a 'personal war'. It is not the responsibility of anyone here to prove anything to you, rather the opposite, it is your responsibility to prove your opinion is worthwhile by ensuring it is free from untested personal bias.
