A tiny Android smartphone designed to be a "companion phone" to a full-sized device has been launched in the US - using the brand name Palm. The handset is the size of a credit card and has two cameras but no headphone jack or wireless charging. It aims to help people take a break from their main phone, the firm said, despite being a fully functioning smartphone in its own right. It has been greeted with bemusement by tech commentators and on social media. The device will cost $349 (£263) and will be available in the US, on the Verizon network only, from November. It is described in its marketing material as "a fully connected product that is in sync with your existing smartphone, so all of your connectivity can go where your smartphone can't".
