Redboard also has a USB mini connector, not the full sized square one that standard Uno has. Personally I'd prefer the mini connector, I've always thought that the USB connector was the most oversized thing on an Arduino board.
The inertia the USB mini connector has in the electronics development arena has annoyed me for years. The connector was deprecated in 2007 and replaced by the rather superior and now very prevalent micro, yet builders just don't seem to want to switch.
