And as for cables, good grief if your cables can't reach from a tower on the floor to the desk, you have other serious issues. My monitor cables are PLENTY long a few times over.
Not everybody is 4'1" tall. I don't know about you, but personally, I've never seen a monitor, usb hub, keyboard or mouse (In the even you're using wired versions) with cables long enough to reach from the desktop to a tower sitting on the floor, when adjusted for somebody who's 5'7" tall let alone somebody over 6'.
All that aside, I'm all for a desk TOP that can be raised to a comfortable height fro working while standing, expressly FOR the purpose of getting out of that sitting position and stretching out a bit without having to bend over to do so. However, any version intended to ONLY be used while standing was clearly designed by someone who has never HAD to be on their feet most of the day much less an entire shift of reception, design, CAD or any other professional capacity that requires being at the desk the majority of the day.
Half an hour of standing in one place and the appeal of that desk will be reduced to nada.
