Like, “What would really be cool is if I didn’t have to line my laptop WiFi antenna up with the Access Point”. That ended up with a patent application for a “self-steering” antenna.
Another example: “What if I didn’t have to install a driver…” ended up being a patent application for devices that install the driver off of the device itself. For instance, you plug in a USB WiFi stick and the driver is downloaded to your PC, configured, and in minutes you are browsing the web.
So any time I hear someone say, “What if”, or “Wouldn’t it be cool” I immediately start paying more attention – because my experience is that something cool might be just ahead…
