I was visiting a hospital, and passed by a seminar room where my eye caught the items in the photo, sitting on a custom stand in the corner.
Remember these? Used to be, they were so ubiquitous that they were instantly recognizable: an overhead foil projector and a circular magazine slide projector.
These days, no one uses them anymore… it’s been years since I even saw one of these. It’s PowerPoint everywhere. In fact this seminar room had a new LCD projector fixed to the ceiling. But these academic institutions are conservative: they throw nothing out. These useless devices may well linger there for years. And so, we are afforded a peek into a not all that distant past..
We got this new HP LaserJet M5035 multifunction printer/copier at my workplace that is very sophisticated and capable. It has a high res touch screen that it uses to accept our commands and to tell us what’s going on.
So today it had a fault and advised me to cycle its power, which I did. The printer then went into a boot sequence, complete with whirring sounds and flashing lights, that took long minutes… very long minutes. 
And all through it, its wonderful display screen showed an HP logo growing larger and smaller, larger and smaller… endlessly. Very neat, but didn’t it occur to the designers of this machine that the user would much prefer a simple text message like “Machine warming up… should be ready in X minutes“?
Many times, a small change in a design makes a product a lot better.
You know the modern version of the office water cooler: a vertical unit that dispenses cold (and in many models, also hot) water into disposable cups. Well, I’ve just seen one that made my day. The unit in the photo, a new model from Tami (a.k.a. Tana Water), has a small but smart addition: the button marked “Room Temp”.
What’s the big deal? Well, in most models, you push the button and get ice-cold water. This must be very attractive if you’ve just jumped off a camel at a desert oasis on a scalding summer day; but in most offices, which are air conditioned, you don’t need it to be ice-cold, and some prefer it not to be. Their solution in the past was to either try to add a little boiling water, or to sip slowly. So now Tami have added the Room Temp button - you can get the same clean, filtered water, without the extra cooling. A tiny redesign, leading to a better product.
With the wonders of Google Maps at our service, we can get some interesting insights. Take the photo below, also viewable here. This is the older part of the Microsoft campus at Redmond, where much of the software in the computer I’m writing this on was developed.
Notice how the buildings all have cross shapes visible in their plans. This is not because of a religious bias in the company’s management. It is, I was told when I visited there, because Bill Gates had decided when he started the company that an effective software engineer needs the peace and quiet made possible by an office with a door. Indeed, while myriads of hi-tech engineers (yours truly included) work in cubicles in the noisy open space made famous by the Dilbert comic strip, Microsoft coders all have their own individual offices with real doors to block out the world when they need to concentrate. Of course such an office requires a window too, or it gets claustrophobic… which explains the shape of the buildings - with a need for so many windows, they had to be made with a convoluted outline, to maximize surface-to-bulk ratio.
For my part, I admire the tenacity - Microsoft moved to Redmond in 1986, and 22 years later they still resist the temptation to compress their engineers into cubes. They have a good thing, and they stick to it!
