Well, the point of these things is that they're supposed to be a step up from a cubicle. Not typically installed in a yard. I can think of all sorts of situations where they would come in handy and make better flexible use of large open spaces. Some of the other configurations shown on the web page are for tiny conference rooms, music practice rooms, tiny retail booths, etc. They might work well to replace the open desks in many older laboratories, which can hardly be used now, due to changing safety regulations.
They remind me a little of some cool stacking dodecahedral desk pods that were in a school magazine back in the 60's. Each kid was isolated inside his own pod, with the open window facing the teacher. They seemed really, really cool at the time.
Having worked from home for 15 years now, I wouldn't necessarily go with one of these, but it is important to separate your working space from the rest of the house. Over these years, the "paperless office" has become a reality, and I no longer need the row of file cabinets or cases of journals that used to require a separate office. However it's still important to have a separate space to "go to work," and more importantly, "leave work behind."
It would also be a lot easier to keep a small space like that "staged" for video conferencing.
