Wasnt as big as we thought it to be I think. I think with all the rumours, we expected a really incremental upgrade. The new iPad Air is however quite a big step up in design, which I prefer and the jump to A7 on both the iPad Air and the Mini Retina was a good choice because my mini seems really sluggish on iOS 7.
I was actually thinking about unlocking with Touch ID on an iPad and it doesn't seem as easy as on the iPhone. If you are holding the iPad in one hand and you try to reach your thumb out to activate the sensor, it seems like you are going to drop the iPad, and thats me on a mini... I think they should have done something with a fingerprint sensor though, even if it was to put it there... Is isn't hard to implement!
The Mac Pro and the MacBook Pros were my favourite part, they seemed really good and the prices seemed perfect, especially for the Mac Pro... Quite cheap for what they have as standard.
I also have a 5S and I feel it is weird sliding to unlock, so much to the extent that I am thinking of selling my mini. I seem to use the MacBook Air more anyway as it seems easier for productivity.
The iPad mini Retina is more expensive because of the new processor and the fact that it is retina. When the iPad 2 was upgraded to Retina, it got a price bump too. The screen really makes it more expensive and the fact that there is Apple Tax
You got a free OS, stop complaining!
