Some inventions inspire awe and then others like Startup Sol Reader’s new E-Ink headset just make you ask, “But why?” At CES, the startup showed off a $350 headset they’re working on that uses e-paper panels for a hands-free experience. I don’t know how I feel about it. It looks cool, but can’t you also “read” hands-free for $20 with an audiobook? Eh, I’ll pass.
