I think if you are going to have floor mounted GPO's, you would also need to have underground dust collection for it to be worth the hassle. I bring my DC line down from the roof at the back corner of the table saw, and I also just bring the power down at the same spot. I would love to not have to bring it down from the ceiling, but it would be too hard to retrofit the DC into the slab.

An hour before the concrete for my shed slab was poured I quickly installed 150mm and 50 mm PVC ducting in the ground so that I could extract dust and run power to the middle of the shed. My TS sits directly over the top of the 150mm ducting and power for my TS and router run through the 50 mm ducting.
I since retrofitted a pair of pressure switches to the TS so that it will not start unless the DC is running. One switch attaches to the OH dust extraction ducting and the other attaches to the TS cabinet PVC port. These switches are connected in series and I ran the OH switch to the cabinet via the same 50 mm PVC ducting that teh power ups through.
Despite the fact that it restricts where the TS sits in the shed I would rate this as one of the best things I have done in my shed.

2011 was a very good year. We had power outlets in the floors at work. Full of dirt and useless.
The concept was to have moveable walls so no power at all if the room designs changed.
And by the grace and wisdom of administrators, they did.
What I saw as the decades rolled on was that every lecturer had their own extension cords for outer wall power.
Up in the laboratories, everything ran along the center core of each bench so no problems for lab equipment
there but BADLY under powered.
My home work shop is just one big downstairs room. My overhead drop box with a quad outlet is just great = nothing in my way.
The wall plug is probably no more than 15A so one at a time, I can run everything as I need them.
With no dedicated, fixed, unmovable conduits, etc, I haven't lost the versatility of the room.
AND, I can slide and twist that island bench to cut 5m 2x4 with ease (open the door and down the hall!).

I have an older shed with existing power outlets.
A centenary wire over head works magic.
Changed it's position heaps of times as I have shifted things about.
If I had an outlet on the floor i am sure it would be in the wrong place forever.

Amen, brother rjtwin501. Amen. Floor plugs can't be kept clean and that's a real safety hazard.
Overhead, hanging down, always clean.
