I've just moved desks at work. Got a really sucky one though - right on the edge where people walk past. No more looking at pr0n at work I guess ;)
It's taken about 2 hours to move though, but that was with zero downtime for my PC. I love UPSes despite them weighing more than the rest of my stuff put together. My journey across the reminded me of those large vehicles that have alarms to warn people they're reverse as the UPS was beeping quite a bit - "Warning: Geek in transit!"
My desk move does have some good points. My net access seems way more faster. I have a bin of my very own. And I managed to throw away all that crap I've been hording on my old desk for the past couple of years. It'll be interesting to see how tidy the old desk is after the cleaners have been in. They'll probably just do their normal routine of shifting stuff (in this case mountains of dust) around the desk.
