By adding a Raspberry Pi (on card computer) in the battery place of the HK Go+Play Boombox you get a very mordern and useful gear!!! You get both a standalone Spotify player controlable  through a webinterface AND an Airplay client for 70-90$!!!

The HK Go+Play has an amasing clear and loud sound, but it lacks connectivity. It was made for an iPad back in time.
You can buy new ones for 250$ or used ones for half...

Raspberry Pi are a ARM powered one card computer that costs 30$ and only needs a USB connection for power and a SD card as "harddisk".
