Looking for reasons to buy an HTC ONE

At the moment I'm using an iPhone 4 and an iPad mini. And I have to say that I love them both.

I use the iPad mostly for watching Youtube and TED video, reading blogs and listening to music and sometimes gaming.

I'm wondering if the HTC ONE could be "the one" device replacing both my iPhone and iPad mini.

Video and sound seem to be great on the HTC ONE. Not sure how much fun reading is...

This is of course super subjective but I would still be interested in what you think.
