This is about the interface on phones.
And for the 1520 metro is much more convenient to use than the new design they've come up with
Aye, and there's the rub - This theory of trying to be universal is going to mean something has to suffer for the sake of other devices. The metro style works great on a phone because of things like small screens and one-handed use. It works
okish on larger touch screens, and is not very useful on traditional PC/monitor/keyboard/mouse setups. This universal idea means we can't simply talk in terms of this being designed for phones, or tablets, or desktops. It has to be useful on all three, and more (xbox, whatever else there is).
I understand
why they want to go to a universal design, and in some ways I might even agree with it, but in use I'm not liking what I'm seeing so far for the phone. For desktop use, yes I'm liking what I'm seeing in W10, but on the phone I'm not caring for the changes I've seen (which of course, are few since tech preview just got released).
Hopefully they achieve some good mix of making both sides of the user base happy, which is definitely going to be a difficult task. How to you make people that want change happy without making people that like the current interface unhappy? That is ultimate designer question.
