This is the first Xiaomi phone I've seent that I find interesting. Having read the description on the Xiaomi website I'm impressed not just by what they've crammed into the device, but the thought they've put into it:
he full-screen slider is fully customizable. Users can slide open the phone to answer calls or customize it to launch different functions.
Are you listening Apple? Instead of a style-driven notch that has led to Apple demanding CSS extensions, they've put some thought into how people might use a bevelless phone. I think particularly the sliding to answer will be popular. Yes, it places higher demands on the mechanics and I'm perfectly happy to stick with a bezel but this has the "Kirk, here" aspect of simplicity of the Razr and the Nokia banana phone and not "you will love the compromise we've come up with".
Looking forward to a review of this when it becomes available.
