Tangram's Smart Dot is the first smart stylus we got our hands on, and it's really quite extraordinary. Styluses are good at doing one thing and one thing only, replacing your finger. The Smart Dot stylus is a genius little gadget accessory for smartphones that's more than good for sketching, drawing and note taking. It's the first app enhanced stylus we've reviewed. With the help of an app, the Smart Dot serves as a powerful wireless presentation and input device delivering an entirely new user experience regular styluses long for. Sounds impressive, as long as it all works in practice that is. Catch the full review down below!
