Yes, nice, I'd love one.
There was a item on the telly the other night about office work and sitting.
A business somewhere encouraged there office staff to move around by having that type of computer desk, so they could stand and work, also with wifi and laptops they also liked to see them working in different areas of the building during the day.
Such as go and talk to office co-worker instead of email. (that is walk).
The office space had been designed to cater for wandering staff and adjustable work surfaces.
It seems even 2 mins of walking every hour or so is much better than a long walk at lunch and none during working time.
