Actually calling it right click is severely under selling it, it has huge advantages for gaming etc. there will be apps that will not be able to be ported to android, at least not usably.
Android supports pressure sensitive touch at the API level since 2009, and There's a phone from 2015 that supports this from huawei. But they didn't create useful interactions with it.
Does it work well? If it does why didn't they incorporate it? You can have double the specs and still be a laggy nightmare.
Yeah and there's bluetooth support too. Wait no, bluetooth on Android is a horrible quivering mess that nobody in there right mind touches.
