For those of you in Austin, TX, there is a local store that sells adjustible height desks[0]. I haven't actually bought one yet, but it was nice to play with them to see what they are like.
Interesting this should come up just now. My (human solution) electric base arrives in 2 days. I bought a finished piece of birch marine plywood for the top. Total cost $674 plus a little elbow grease to trim to size and sand. :D
It does seem ridiculously expensive for a motor to drive the desktop up and down. But I'm trying to fix a shoulder injury that seems to have gone chronic. We shall see...
Thanks for the link. The desks look gorgeous, but I'll be honest: the absence of even ballpark pricing and the presence of prominent financing offers make me a bit leery of looking further.
My work has a similar model. They're quite nice, and I've gradually been working on how much I'm standing - up to about 2 hours now.
As far as power goes, my desk has a hidden power strip on the underside. It powers the lift feature for both legs (so there's only 1 wall plug), but you can also plug in your monitors so you don't need to have 10' cords on all your equipment. They also sell a power strip that can mount to the top of the desk, so again you don't need very long cords for all your peripherals (phones, chargers, etc).
For network cables you'll still need a cord long enough to travel to the standing height.
I tend to be a neat freak when it comes to organizing a desk, and will often have a surge strip velcro'd to the underside of a desk. Industrial velcro & straps are pretty cheap, and can be adjusted pretty easily when moving/relocating equipment. I've been thinking of getting monitor arms, since I am fairly tall, I tend to want my desk lower (at elbow height) and my monitors higher than most will rise up from that height, so that I can actually sit up straight and look forward... I'm pretty heavy so don't think going straight to a standing desk would work as well for me.
