I’m going to chime in and say I agree. It seems like the simplest way to clean things up (without an actual device redesign) would be to switch to a power supply with a right angle plug. It would allow users to rotate it up, down, or back as they see fit. It would require less clearance for those like marlowkc using enclosures, and I’m finding it hard to think of a down-side. (Perhaps those with arthritic fingers might find it more difficult to grasp?)
Maybe a thoughtful option might be to offer a simple adaptor for those that wish to use them.
