I have a standing desk.
I like it. But I can't honestly say I use it a lot. I try to make it a habit of starting off my day using it for 1 hour or so. In reality I use it like this maybe once a week. I actually like it the most for when I'm super busy and I'm doing work on 2 PC's simultaneously (the 2nd PC is on a second desk behind me). Running back and forth when I have the standing set-up is kinda handy.
The cables are an issue. They're all just dangling, and I can't see much possibility of cleaning it all up without investing lots of time and extra cost in longer cables.
It's a big desk, with a big motor so it did cost a bit. But I trust it to handle the load of 2 screens (though they're only lightweight 27inch). The PC is on the ground. My first thought when I started using it was that it might have been smarter to tether the PC tower to the desk, so when it goes up/down, the PC follows and theoretically the only cable that needs to move with it is the power. Now I have 2x HDMI, 2x Monitor power, mouse, speaker, USB charging, microphone, lamp, webcam cables all moving up/down with the table and it is quite messy.
The only other issue I can raise is that I'd like the desk motor to have memory (settings). I noticed when I lifted it up I instantly forgot what height i liked the table at. 1 or 2 cm difference made my back hurt big time. So I simply drew lines on the legs to indicate when I'm at the right height.
Good luck mate.
