Are all small gadgets worthless? No, but I do hope that in the future manufactures will make functionality a higher priority and focus less on saving a few centimeters here and there. Gadgets like cell phones do need to be small, but not so tiny that they lose in practicality what they gain in portability. If an item fits comfortably into a pocket, then most of us aren’t going to be overly eager to downsize based solely on size if it costs us features. So hopefully the trend of making tiny gadgets just for the sake of simply doing so will end, and going forward, manufactures will find ways to better combine form and functionality.
