Currently in development - When you're at corporate headquarters or heading for a meeting it's a classic briefcase, but when your riding home on your bike it converts into a great backpack. Meanwhile the detachable laptop/tablet frame with keyboard can be used for a convenient desktop work station. Another option is an audio amplifier with speakers to enhance your sound. Top it all off with the on board cellphone/tablet charger and you're completely mobile for days. Please take a look at a YouTube video for the Briefcase/Backpack or for more information please contact Loren
