The HP Amp with built-in Bluetooth speakers brings a new dimension to multifunctionality. Designed to save space in homes and home offces, it combines the best features of a Bluetooth portable speaker, desktop speakerphone and multifunction printer. There is even a convenient USB port for charging portable devices. The accompanying HP Smart app lets you scan to and print from a smartphone, stream your favourite music, take calls on the printer and order replacement ink. The only bum note? There are no plans to launch it in the UK.
