Sandisk have been making dual-port usb flash drives for years. I see no reason to buy/use any other kind, in the same way I see no reason buy a printer with a parallel port or a mouse with a ps2 plug on it.

If it's really a significant problem, use the benefits of usb and put a hub or usb extension cord on the desk to connect to.

I just cannot fathom how such trivial factors are a problem for people.
