Google Hangout destroys my computer. If I had any sort of expertise in building hardware, I’d start a company to produce dead-simple dedicated video conferencing hardware.
It would be an all-in-one device (both camera and display) where I can have an instant-on connection with anyone in the world. And, to get fancy, the optics of the camera would correct for the orientation of the device, such that it would always appear as though I’m having a face-to-face conversation (instead of nose to face or forehead to nose).
A price point of $500 or less would make this a killer device for any company.
