The smartphone race is hotter than ever with manufacturers trying to convince buyers to choose their phones. That's why you see things like curved screens, edge screens, fingerprint scanners, fancy materials and other "Wow" features.
While some of these features sometimes work, many of them turn out to be gimmicks that don't quite pan out. Or, like fingerprint sensors, they take a while to really find a use, as in the case of Apple Pay.
That's why I'm taking this new smartphone feature from Lenovo with a grain of salt. It's called Smart Cast and it's a smartphone with a laser projector built in.
Smart Cast works can display images from the smartphone on to walls. It's self focusing so you don't have to do any adjustment.
