When I was a cook way back in the day, I learned a valuable lesson. Due to the small sizes of kitchens, you simply can’t fit loads of equipment in that tiny space. So what you do buy has to have multiple functions. The most famous is the 10” or 12” chef knife. It’s a great spatula, spoon, and of course a knife. So this fact holds true with pretty much anything I get now. If I can’t get multiple uses out of pretty much anything, it’s pointless to me. So I’m surprised when people ask me the point with glass whiteboards. Let me add a bit more to my fact of life; when something has multiple uses it have various points of ROI. Basically makes you money via saving you money. A glass whiteboards ROI is because it is multifunctional and due to its durability, never really needs replacing.
