DaCostaBR: I think the people who sing its praises from the rooftops forget its one fatal flaw: it's really fucking unconfortable.
Oh yep, but think of it as something transitory. 85% of the time you're standing...
vicklemos: Yay or nay? Personally I think it's a terrific idea.
timppu: Nay. I tried it at work, I just couldn't concentrate as well as I can while sitting down.
Also, I seem to recall the health benefits of simply standing (instead of sitting) have been later revealed to be overly exaggerated, ie. it isn't that beneficial after all. Sorry I don't have a link, I just recall reading that in some newspaper one or two months ago.
You're right imho when it comes to focus, I guess. Mundane stuff is easily done while standing, thoughtful thinking can be a bit tricky to master and tough to bear.
But.. but dude ;P
The benefits are incredibly real, in the short term, I say. Trust me, wouldn't be stating it if it wasn't as near as solid ;P
