I recently searched for and purchased a USB multiport for my laptop but was disappointed that I could not find one that attached directly to my laptop port without a cable. The cable allows the multliport to 'dangle', risking damage or loss. Can you build one that is compact, has three or four ports to the outside, a single male extension on one side to 'mate' snugly with my laptop? Adjustable clips to keep it securely fastened would be very important...even velcro attachments might work.
That's my idea, I hope someone can develop it! (I have a Google Sketchup drawing but was't able to insert it.)
