modu is a new mobile phone concept that features a full system of modular jackets that add deeper
functionality to the basic phone. the basic modu is the world’s lightest phone, boasting 2gb of memory
and music playing functionality. this device feature’s a small screen and 7-digit keypad. its domino-like
design is fully functional on its own, but the newly launched jackets enhance it for specific functions.
the modu phone simply inserts into the jackets, acting as its computer source. this allows users to change
their phone without purchasing a whole new unit or losing their information. the modular design also
allows user to plug their modu into other devices like speakers or a digital picture frame. the modu,
a selection of jackets and some accessories were launched earlier this month at the mobile world
congress in barcelona.
