The only ONE
Whenever I have a play with a HTC One I do love the device BUT - those speakers top and bottom make it feel huge for a 5" phone. That wouldn't be an issue if the One Mini took Sony's approach and just gave you a smaller version of the One. But it doesn't. Assuming they keep to the practices of the earlier One Mini models you end up with a distinctly mid-range spec at an eye-wateringly top-end price.
Which is a real shame as I do think it is a brilliant phone.
